Abstract

A display apparatus has a display panel having a display region, a light shielding region surrounding the display region, and an outer region located outside of the light shielding region; a support frame disposed at a rear surface side of the display panel, the support frame including a panel supporting portion which supports a peripheral portion of the display panel from a rear side, and an extension beginning from the panel supporting portion and extending away from the display panel; and a light shield disposed at the rear surface side of the display panel, the light shield including a light-shielding portion which is disposed between the display panel and the support frame, the light-shielding portion extending so as to overlap at least a portion of the light shielding region and the outer region of the display panel as viewed from a normal direction of the display panel, and a fixture portion beginning from the light-shielding portion and extending away from the display panel, the fixture portion being fixed to the extension of the support frame.

First claim

What is claimed is:

1. A display apparatus comprising:
a display panel having a display region in which to display an image, a light shielding region surrounding the display region, and an outer region located outside of the light shielding region;
an optical sheet disposed at a rear surface side of the display panel so as to overlap at least the display region of the display panel as viewed from a normal direction of the display panel;
a support frame disposed at a rear surface side of the display panel, the support frame including
a panel supporting portion which supports a peripheral portion of the display panel from a rear side,
a sheet supporting portion which projects inward from the support frame to support a peripheral portion of the optical sheet from a rear side, the sheet supporting portion being located inside of the panel supporting portion, and
an extension beginning from the panel supporting portion and extending away from the display panel; and

a light shield disposed at the rear surface side of the display panel, the light shield including
a light-shielding portion which is disposed between the display panel and the support frame, the light-shielding portion extending so as to overlap at least a portion of the light shielding region and the outer region of the display panel as viewed from the normal direction of the display panel, and
a fixture portion beginning from the light-shielding portion and extending away from the display panel, the fixture portion being fixed to the extension of the support frame, wherein,

as viewed from the normal direction of the display panel, an end surface of the optical sheet is located inside of the panel supporting portion and the extension,
the fixture portion of the light shield has at least one aperture; and
the extension of the support frame includes at least one hook portion which is insertable in the at least one aperture to fix the fixture portion at a predetermined position relative to the extension.

2. A display apparatus comprising:
a display panel having a display region in which to display an image, a light shielding region surrounding the display region, and an outer region located outside of the light shielding region;
a backlight section disposed at a rear surface side of the display panel;
an optical sheet disposed between the backlight section and the display panel so as to overlap at least the display region of the display panel as viewed from a normal direction of the display panel;
a support frame disposed at the rear surface side of the display panel, the support frame including
a panel supporting portion which supports a peripheral portion of the display panel from a rear side,
a sheet supporting portion which projects inward from the support frame to support a peripheral portion of the optical sheet from a rear side, the sheet supporting portion being located inside of the panel supporting portion, and
an extension beginning from the panel supporting portion and extending away from the display panel; and

a light shield disposed at the rear surface side of the display panel, the light shield including
a light-shielding portion which is disposed between the display panel and the support frame and optical sheet, the light-shielding portion extending so as to overlap at least a portion of the light shielding region and the outer region of the display panel as viewed from the normal direction of the display panel, and
a fixture portion beginning from the light-shielding portion and, on an outside of the extension, extending away from the display panel, the fixture portion being fixed to the extension of the support frame, wherein,

as viewed from the normal direction of the display panel, an end surface of the optical sheet is located inside of the panel supporting portion and the extension, the end surface of the optical sheet being located at an interspace from the panel supporting portion of the support frame, the interspace overlapping the light-shielding portion as viewed from the normal direction of the display panel.

3. The display apparatus of claim 1 , wherein the fixture portion includes a plurality of portions that are disposed at intervals along a peripheral direction.

4. The display apparatus of claim 2 , wherein,
the backlight section is an edge light type backlight section including a light guide plate and a light source which causes light to be incident on a side surface of the light guide plate; and
the light shield is disposed so as to overlap the entire light source as viewed from the normal direction of the display panel.

5. The display apparatus of claim 2 , wherein the fixture portion is adhesively bonded directly to an outer side surface of the extension.

6. The display apparatus of claim 2 , wherein the light shield comprises an elastic member.

7. The display apparatus of claim 2 , wherein,
the fixture portion of the light shield has at least one aperture; and
the extension of the support frame includes at least one hook portion which is insertable in the at least one aperture to fix the fixture portion at a predetermined position relative to the extension.

8. The display apparatus of claim 2 , further comprising a diffuser disposed between the backlight section and the optical sheet, wherein
the sheet supporting portion of the support frame is located between the diffuser and the optical sheet.

9. The display apparatus of claim 1 , wherein the light shield is black in color.

10. The display apparatus of claim 2 , wherein the fixture portion includes a plurality of portions that are disposed at intervals along a peripheral direction.

11. The display apparatus of claim 2 , wherein the light shield is black in color.

12. The display apparatus of claim 2 , wherein, the fixture portion is fixed directly to an outer side surface of the extension of the support frame.

13. A display apparatus comprising:
a display panel having a display region in which to display an image, a light shielding region surrounding the display region, and an outer region located outside of the light shielding region;
a backlight section disposed at a rear surface side of the display panel;
an optical sheet disposed between the backlight section and the display panel so as to overlap at least the display region of the display panel as viewed from a normal direction of the display panel;
a support frame disposed at the rear surface side of the display panel, the support frame including
a panel supporting portion which supports a peripheral portion of the display panel from a rear side,
a sheet supporting portion which projects inward from the support frame to support a peripheral portion of the optical sheet from a rear side, the sheet supporting portion being located inside of the panel supporting portion, and
an extension beginning from the panel supporting portion and extending away from the display panel; and

a light shield disposed at the rear surface side of the display panel, the light shield including
a light-shielding portion which is disposed between the display panel and the support frame and optical sheet, the light-shielding portion extending so as to overlap at least a portion of the light shielding region and the outer region of the display panel as viewed from the normal direction of the display panel, and
a fixture portion beginning from the light-shielding portion and extending away from the display panel, the fixture portion being fixed to the extension of the support frame, wherein,

as viewed from the normal direction of the display panel, an end surface of the optical sheet is located inside of the panel supporting portion
