Abstract

The present invention provides a display apparatus capable of reliably mounting at least one of a holding member and a bezel to a holding plate with no damage to a light emitting element mounting substrate by a simple structure without providing a mounting member, and coping with an increase in an area of a driving circuit board disposed to the holding member. The display module of a TV receiving apparatus includes a light guide plate, a holding plate which holds a substrate having a plurality of LEDs, and is disposed to face a side surface of the light guide plate, a display panel disposed to face a main surface of the light guide plate, a holding member which covers the holding plate and holds the display panel, and a bezel which covers a peripheral edge part of the display panel and the holding member. The holding plate is provided with a mounting part which extends and protrudes in a direction which is away from the display panel, and at least one of the holding member and the bezel is mounted to the mounting part by a screw.

Claims

1. A display apparatus comprising:

a light guide plate, a holding plate which holds a substrate having a plurality of light emitting elements, and is disposed to face a side surface of the light guide plate, a display panel disposed to face a main surface of the light guide plate, a holding member which holds the display panel and covers the holding plate, and a bezel which covers a peripheral edge part of the display panel and the holding member,

wherein the holding plate is provided with a mounting part which extends and protrudes in a direction which is away from the display panel,

the holding member is provided with a bezel abutting part which protrudes in a direction close to the bezel and abuts on the rear surface of the bezel, and

both of the holding member and the bezel are mounted to the mounting part by a fastener;

wherein

the fastener is a screw,

a female screw is formed in the mounting part, and

the bezel has a screw head locking at which a peripheral edge part of a head portion of the screw is locked and a screw insertion hole into which a leg of the screw is inserted,

wherein

the bezel abutting part abuts on the screw head locking, and

in a state in which the peripheral edge part is locked at the screw head locking and the leg is inserted into the screw insertion hole, the screw is screwed to the female screw.

2. The display apparatus according to claim 1, wherein in the case where a plurality of driving circuit boards to drive the display panel are placed on the holding member at the outside of the portion with which the holding plate is covered, a fastening portion by the screw is between adjacent driving circuit boards.

3. The display apparatus according to claim 2, wherein a concave is formed at a portion at which the driving circuit board faces toward the adjacent driving circuit board.

4. The display apparatus according to claim 1, wherein in the case where a plurality of driving circuit boards to drive the display panel are placed on the holding member at the outside of the portion with which the holding plate is covered, a fastening portion by the screw is an end portion in the longitudinal direction of the holding member, in which the driving circuit board is not provided.

5. The display apparatus according to claim 1, wherein in the case where a plurality of driving circuit boards to drive the display panel are placed on the holding member at the outside of the portion with which the holding plate is covered, a fastening portion by the screw is a distal portion from the display panel, with respect to the portion in which the driving circuit board of the holding member is provided.

6. The display apparatus according to claim 1, wherein the mounting part is provided with a second bezel abutting part which protrudes in a direction close to the bezel and abuts on the rear face of the screw head locking.

7. The display apparatus according to claim 2, wherein the mounting part is provided with a second bezel abutting part which protrudes in a direction close to the bezel and abuts on the rear face of the screw head locking.

8. The display apparatus according to claim 5, wherein the mounting part is provided with a second bezel abutting part which protrudes in a direction close to the bezel and abuts on the rear face of the screw head locking.

9. The display apparatus according to claim 1, wherein the bezel abutting part has a shape for the screw to be inserted into the bezel abutting part.

10. The display apparatus according to claim 2, wherein the bezel abutting part has a shape for the screw to be inserted into the bezel abutting part.

11. The display apparatus according to claim 3, wherein the bezel abutting part has a shape for the screw to be inserted into the bezel abutting part.

12. The display apparatus according to claim 5, wherein the bezel abutting part has a shape for the screw to be inserted into the bezel abutting part.

13. The display apparatus according to claim 1, comprising a covering plate which covers a flat surface of the light guide plate, and is provided perpendicular to the holding plate.

14. The display apparatus according to claim 2, comprising a covering plate which covers a flat surface of the light guide plate, and is provided perpendicular to the holding plate.

15. The display apparatus according to claim 5, comprising a covering plate which covers a flat surface of the light guide plate, and is provided perpendicular to the holding plate.

16. The display apparatus according to claim 1, wherein the mounting part is provided with fins to dissipate heat.

17. The display apparatus according to claim 2, wherein the mounting part is provided with fins to dissipate heat.

18. The display apparatus according to claim 5, wherein the mounting part is provided with fins to dissipate heat.
