Abstract

This display device ( 100 ) includes: a display panel ( 10 ); a light-transmitting cover ( 20 ) which is arranged closer to a viewer than the display panel is so as to cover the display panel and which includes a lens portion at a position corresponding to an end portion of the display panel; and a bezel ( 30 ) including a side frame portion which covers the side surface of the display panel at least partially. The bezel ( 30 ) further includes a fixing portion ( 34 ) which is arranged at the tip of the side frame portion and in the vicinity of the side surface of the light-transmitting cover. The light-transmitting cover ( 20 ) and the fixing portion ( 34 ) of the bezel ( 30 ) are directly fixed to each other.

First claim

The invention claimed is:

1. A display device comprising:
a display panel;
a light-transmitting cover which is closer to a viewer than the display panel so as to cover the display panel and which includes a lens portion at a position corresponding to an end portion of the display panel; and
a bezel including a side frame portion which at least partially covers a side surface of the display panel, wherein
the bezel further includes a fixing portion which is at a tip of the side frame portion and in the vicinity of a side surface of the light-transmitting cover,
the light-transmitting cover and the fixing portion of the bezel are directly fixed to each other,
the light-transmitting cover includes a notched portion, which is directly fixed onto the fixing portion of the bezel,
the fixing portion of the bezel has a bent tip portion, the notched portion of the light-transmitting cover has a groove, of which a shape of the notched portion matches a shape of the bent tip portion, and
the bent tip portion and the notched portion are filter into each other.

2. The display device of claim 1 , wherein a viewer-side surface of the display panel and a back surface of the light-transmitting cover are not directly fixed to each other.

3. The display device of claim 1 , wherein the fixing portion of the bezel is arranged so as to project out of the viewer-side surface of the display panel.

4. The display device of claim 3 , wherein the display panel has a display area and a non-display area which is arranged outside of the display area, and
the fixing portion of the bezel is arranged at such a position as not to prevent light that has been emitted from the end of the display area from passing through the lens portion of the light-transmitting cover and then traveling perpendicularly to the display panel.

5. The display device of claim 1 , wherein a gap is left between an end of the bent tip portion and a bottom of the groove of the notched portion of the light-transmitting cover.

6. The display device of claim 1 , further comprising a metallic member which covers the notched portion of the light-transmitting cover at least partially.

7. A display device comprising:
a display panel;
a light-transmitting cover which is closer to a viewer than the display panel so as to cover the display panel and which includes a lens portion at a position corresponding to an end portion of the display panel; and
a bezel including a side frame portion which at least partially covers a side surface of the display panel, wherein
the bezel including a fixing portion which is at a tip of the side frame portion and in the vicinity of a side surface of the light-transmitting cover,
the light-transmitting cover and the fixing portion of the bezel are directly fixed to each other, and
the fixing portion of the bezel has a hole which faces the light-transmitting cover, and the bezel and the light-transmitting cover are secured to each other with a fixing member that passes through the hole.

8. The display device of claim 1 , wherein the light-transmitting cover and the bezel are bonded together with an adhesive member interposed between the fixing portion of the bezel and the light-transmitting cover.

9. A display device comprising:
a display panel;
a light-transmitting cover which is closer to a viewer than the display panel so as to cover the display panel and which includes a lens portion at a position corresponding to an end portion of the display panel; and
a bezel including a side frame portion which at least partially covers a side surface of the display panel, wherein
the bezel further includes a fixing portion which is at a tip of the side frame portion and in the vicinity of a side surface of the light-transmitting cover,
the light-transmitting cover and the fixing portion of the bezel are directly fixed to each other,
the display panel has a substantially rectangular planar shape,
the bezel includes first and second bezel portions which are arranged so as to respectively face first and second sides of the display panel that are opposed to each other, and
the first and the second bezel portions have mutually different thicknesses.

10. The display device of claim 9 , wherein the display panel has a display area and a non-display area which is arranged outside of the display area,
the width of the non-display area is broader on the first side than on the second side, a terminal region is arranged in the non-display area along the first side, and
the first bezel portion is less thick than the second bezel portion.

11. The display device of claim 1 , wherein a central portion of the light-transmitting cover has been formed to be thinner than a peripheral portion of the light-transmitting cover.

12. The display device of claim 1 , wherein a gap is left between a viewer-side surface of the display panel and a back surface of the light-transmitting cover and is filled with the air.

13. The display device of claim 1 , wherein a gap is left between a viewer-side surface of the display panel and a back surface of the light-transmitting cover and is filled with a filler, of which the refractive index is greater than 1.0 and the shear storage modulus G′ is equal to or smaller than 10 6 Pa.
