Abstract

A display apparatus, comprising: a display panel configured to display an image; a support plate which is disposed on a rear side of the display panel and supports a light source; and a support cylinder which is disposed between the support plate and the display panel, which is provided along an edge portion of the support plate, and which is made up of a plurality of sheet metal members.

First claim

The invention claimed is:

1. A display apparatus, comprising:
a display panel configured to display an image;
a support plate which is disposed on a rear side of the display panel and supports a light source on a front surface of the support plate; and
a support member which is disposed between the support plate and the display panel, which is provided along an edge portion of the support plate, and which includes a square pipe with a rectangular cross section orthogonal to an axial direction of the square pipe,
wherein the square pipe comprises:
a first side part which is fixed at an edge part of the front surface of the support plate;
a second side part which is opposite to the first side part and located close to the display panel;
a third side part which connects the first side part and the second side part; and
a fourth side part which is opposite to the third side part and located closer to a center part of the support plate than the third side part and connects the first side part and the second side part, and

the support member is made up of a plurality of sheet metal members.

2. The display apparatus according to claim 1 , wherein
the plurality of sheet metal members includes:
a first sheet metal member which comprises at least the first side part, the second side part, and the third side part; and
a second sheet metal member which comprises at least the fourth side part.

3. The display apparatus according to claim 2 , wherein
the support member further comprises an extending part extending toward the center part of the support plate parallel to the first side part from a connection part of the first side part and the fourth side part,
the first side part and the extending part are fixed at the edge part of the front surface of the support plate,
the first sheet metal member further comprises the extending part and a part of the fourth side part close to the second side part, in addition to the first side part, the second side part and the third side part,
the second sheet metal member further comprises the extending part or comprises the extending part and a part of the second side part close to the fourth side part, in addition to the fourth side part, and
the first sheet metal member and the second sheet metal member are joined at a overlapped part of the first sheet metal member and the second sheet metal member.

4. The display apparatus according to claim 3 , wherein
the support member further comprises a protruding part protruding to the display panel from an edge part of the extending part which is close to a center part of the support plate, and
the protruding part is made up of the first sheet metal member and the second sheet metal member.

5. The display apparatus according to claim 1 , wherein
a panel support part is provided between the support member and the display panel to support the display panel,
the panel support part includes a front panel part opposite to the second side part and a side panel part connected to the front panel part approximately perpendicular to the front panel part,
the third side part is provided with a holding hole configured to hold the panel support part, and
the side panel part of the panel support part has a fitting part which is fitted to the holding hole.

6. The display apparatus according to claim 5 , wherein
the second side part has a positioning protrusion configured to protrude to the front panel part and position the panel support part, and
the front panel part of the panel support part is provided with a positioning hole with which the positioning protrusion is engaged.

7. The display apparatus according to claim 6 , wherein
the plurality of sheet metal members comprises:
a first sheet metal member which comprises at least the first side part, the second side part, and the third side part; and
a second sheet metal member which comprises at least the fourth side part, and
the positioning protrusion is formed by cutting and raising a part of the third side part of the first metal sheet member.

8. The display apparatus according to claim 1 , wherein
a panel support part is provided between the support member and the display panel to support the display panel,
the panel support part includes a front panel part opposite to the second side part and a side panel part connected to the front panel part approximately perpendicular to the front panel part,
the second side part has a positioning protrusion configured to protrude to the front panel part and position the panel support part, and
the front panel part of the panel support part is provided with a positioning hole with which the positioning protrusion is engaged.

9. The display apparatus according to claim 8 , wherein
the plurality of sheet metal members comprises:
a first sheet metal member which comprises at least the first side part, the second side part, and the third side part; and
a second sheet metal member which comprises at least the fourth side part, and
the positioning protrusion is formed by cutting and raising a part of the third side part of the first metal sheet member.

10. The display apparatus according to claim 1 , wherein
