Abstract

Disclosed herein is a display device including a display panel having a display portion configured to display an image, a plate-shaped member having a first principal surface and a second principal surface, the display panel being disposed on a second principal surface side, the plate-shaped member including a screen portion disposed in a position corresponding to the display portion, an opaque frame member disposed at a peripheral edge of the screen portion, a bonding member that has transparency and is configured to bond the display panel and the plate-shaped member to each other, a holding member disposed on the second principal surface side of the plate-shaped member, and a fixing member configured to fix the frame member and the holding member to the plate-shaped member, the plate-shaped member further including a transparent peripheral edge portion disposed on an outside of the frame member.

Claims (36)

1. A display device comprising:

a display panel having a display portion configured to display an image;

a plate-shaped member having a first principal surface and a second principal surface, the display panel being disposed on a second principal surface side, the plate-shaped member including a screen portion disposed in a position corresponding to the display portion;

an opaque frame member disposed at a peripheral edge of the screen portion;

a bonding member that has transparency and is configured to bond the display panel and the plate-shaped member to each other;

a holding member disposed on the second principal surface side of the plate-shaped member; and

a fixing member configured to fix the frame member and the holding member to the plate-shaped member;

the plate-shaped member further including a transparent peripheral edge portion disposed on an outside of the frame member.

2. The display device according to claim 1 , wherein

the plate-shaped member has a frame-shaped groove formed between the screen portion and the peripheral edge portion as viewed from a front of the display device, and

the frame member is housed in the groove.

3. The display device according to claim 2 , wherein

a surface on a first principal surface side of the frame member is flush with the first principal surface in a state in which the frame member is housed in the groove.

4. The display device according to claim 1 , wherein

the fixing member includes a plurality of fastening members configured to fix the frame member and the holding member by fastening the frame member and the holding member, and

the frame member includes a boss member fixed by the plurality of fastening members and a decorated member disposed closer to a first principal surface side than the boss member.

5. The display device according to claim 4 , wherein

a whole of the boss member coincides with the decorated member as viewed from a front of the display device.

6. The display device according to claim 1 , wherein

at least one of the frame member and the holding member has higher rigidity than that of the plate-shaped member.

7. The display device according to claim 6 , wherein

the plate-shaped member is formed of a resin having transparency, and

the at least one of the frame member and the holding member is formed of a metal.

8. The display device according to claim 1 , wherein

the plate-shaped member includes a base material formed of polycarbonate and a hard coat layer formed on a front surface of the base material.

9. The display device according to claim 1 , wherein

the holding member includes a frame-shaped frame member that at least partly coincides with the frame member as viewed from a front of the display device.

10. The display device according to claim 9 , wherein

the holding member further includes a heat radiating member configured to radiate heat generated by the display panel, and

the frame member is disposed at a peripheral edge of the heat radiating member, and has higher rigidity than that of the heat radiating member.

11. The display device according to claim 1 , wherein

the holding member is disposed in a position not coinciding with the peripheral edge portion as viewed from a front of the display device.

12. The display device according to claim 1 , wherein

the screen portion of the plate-shaped member is transparent.

13. The display device according to claim 1 , wherein

the display panel is an organic electro-luminescence display panel.
