Abstract

A display device of the disclosure includes: a display panel; a decorative member that holds the display panel; and a light guide plate that has rigidity and includes an edge surface attached to the decorative member.

Claims (31)

1. A display device, comprising:

a display panel;

a decorative member that holds the display panel;

a light guide plate that has rigidity and includes an edge surface attached to the decorative member, wherein the light guide plate and the decorative member are attached in an interspaced state by an adhesive layer having a plurality of interspaced portions extending from the edge surface of the light guide plate to a surface of the decorative member facing the edge surface of the light guide plate; and

an optical sheet disposed in a suspended state along the edge surface of the light guide plate, the optical sheet having a first member and a second member, the first member disposed directly on a first surface of the light guide plate that extends in a lengthwise direction of the light guide plate and the second member disposed directly on a second surface of the light plate that extends in a depthwise direction of the light guide plate so as to form a lug, the lug having an opening operable to dispose the optical sheet in the suspended state.

2. The display device according to claim 1 , wherein the light guide plate includes a glass base.

3. The display device according to claim 1 , wherein the optical sheet is provided on a display-surface side with respect to the light guide plate.

4. The display device according to claim 1 , wherein the adhesive layer is provided in a region other than the lug of the optical sheet.

5. The display device according to claim 1 , further comprising a reflection polarizing film, wherein

the display panel includes a first substrate, a display layer, and a second substrate that are stacked in order, and

the reflection polarizing film is disposed on an opposite surface to the display layer of the first substrate.

6. The display device according to claim 1 , wherein the display panel is attached to the decorative member, with a second adhesive layer made of a soft resin material in between.

7. The display device according to claim 1 , further comprising a rear sheet disposed on a rear surface of the light guide plate.

8. The display device according to claim 1 , further comprising a heat sink with a bent surface that extends around a portion of a lower surface of the light guide plate wherein a light source is disposed on a first portion of the bent surface of the heat sink.

9. The display device according to claim 8 , wherein the bent surface of the heat sink comprises a cornered surface having a second portion extending in a different direction than the first portion and along a lengthwise direction of the light guide plate.

10. The display device according to claim 8 , wherein the heat sink is disposed on a rear surface of a reflection sheet and the reflection sheet is disposed on a rear surface of the light guide plate.

11. The display device according to claim 1 , wherein the lengthwise direction of the light guide plate is orthogonal to the depthwise direction of the light guide plate.

12. The display device according to claim 1 , further comprising a plurality of metal plates positioned along a rear surface of the display device, the plurality of metal plates allowing for support of the display device on an external surface.

13. The display device according to claim 12 , wherein the plurality of metal plates are positioned internal to the display device between a rear surface of the light guide plate and a back chassis of the display device.

14. A display device comprising:

a display panel;

a decorative member that holds the display panel;

a light guide plate that has rigidity and includes an edge surface attached to the decorative member;

a sealing member provided in a periphery of the display panel, the sealing member including a surface that is level with a display surface of the display panel; and

an optical sheet disposed in a suspended state along the edge surface of the light guide plate, the optical sheet having a first member and a second member, the first member disposed directly on a first surface of the light guide plate that extends in a lengthwise direction of the light guide plate and the second member disposed directly on a second surface of the light plate that extends in a depthwise direction of the light guide plate so as to form a lug, the lug having an opening operable to dispose the optical sheet in the suspended state.

15. The display device according to claim 14 , further comprising a bonding film bonded to a front surface of the display panel and a front surface of the sealing member.

16. The display device according to claim 14 , further comprising a heat sink having a bent surface that extends around a portion of a lower surface of the light guide plate, wherein a light source is disposed on a first portion of the bent surface of the heat sink.

17. The display device according to claim 16 , wherein the bent surface of the heat sink comprises a cornered surface having a second portion extending in a different than the first portion and along a lengthwise direction of the light guide plate.

18. The display device according to claim 14 , further comprising a heat sink having a bent surface that extends around a portion of a lower surface of the light guide plate wherein the heat sink is disposed on a rear surface of a reflection sheet and the reflection sheet is disposed on a rear surface of the light guide plate.

19. The display device according to claim 14 , wherein the lengthwise direction of the light guide plate is orthogonal to the depthwise direction of the light guide plate.

20. The display device according to claim 14 , further comprising a plurality of metal plates positioned along a rear surface of the display device, the plurality of metal plates allowing for support of the display device on an external surface.
