Abstract

A display device includes a display panel configured to display an image, a light blocking member under the display panel, a bracket facing the display panel such that the light blocking member is between the display panel and the bracket, a bridge member between the light blocking member and the bracket, and configured to support a position of the light blocking member and the bracket, and a buffer member at a same layer as the bridge member, and contacting the bridge member.

First claim

What is claimed is:

1. A display device comprising:
a display panel configured to display an image;
a light blocking member below the display panel for blocking light incident to the display panel;
a bracket facing the display panel such that the light blocking member is between the display panel and the bracket;
a bridge member between the light blocking member and the bracket, and configured to support a position of the light blocking member and the bracket; and
a buffer member mounted on a same layer as the bridge member and contacting sides of the bridge member,
wherein the bridge member is non-overlapped by the buffer member in a thickness direction, and
wherein the bridge member is disposed in an enclosed space defined by the light blocking member, the bracket, and the buffer member.

2. The display device of claim 1 , wherein the bridge member is surrounded by the buffer member when viewed in a plan view.

3. The display device of claim 2 , wherein the bridge member extends along a direction in which at least an edge of the display panel extends.

4. The display device of claim 2 , wherein the bridge member is provided in a plural number, and wherein the bridge members are spaced from each other at regular intervals.

5. The display device of claim 2 , wherein the bridge member extends along a periphery of the display panel.

6. The display device of claim 2 , wherein an area of the bridge member is less than an area of the buffer member when viewed in a plan view.

7. The display device of claim 2 , wherein a thickness of the bridge member is the same as a thickness of the buffer member, and
wherein a lower surface of the buffer member contacts an upper surface of the bracket.

8. The display device of claim 2 , wherein the bridge member comprises at least one of a polyethylene terephthalate, a stainless steel, or a resin.

9. A display device comprising:
a display panel including a display area configured to display an image and a non-display area adjacent to the display area;
a light blocking member at a lower surface of the display panel for blocking light incident to the display panel;
a buffer member at a lower surface of the light blocking member;
a bridge member at the lower surface of the light blocking member, at least a portion of the bridge member being overlapped by the display area of the display panel when viewed in a plan view; and
a bracket facing the display panel such that the light blocking member, the buffer member, and the bridge member are between the bracket and the display panel.

10. The display device of claim 9 , further comprising a heat discharge member between the buffer member and the bracket, and overlapping the buffer member,
wherein the bridge member penetrates through the buffer member and the heat discharge member.

11. The display device of claim 10 , wherein the heat discharge member comprises graphite.

12. The display device of claim 10 , further comprising a radiating member between the heat discharge member and the bracket, and overlapping the heat discharge member and the bridge member.

13. The display device of claim 12 , wherein a side surface of the bridge member is surrounded by the buffer member and the heat discharge member.

14. The display device of claim 12 , wherein the bridge member couples the buffer member and the radiating member.

15. The display device of claim 12 , wherein a thickness of the bridge member is substantially equal to a distance between the light blocking member and the radiating member.

16. A portable terminal comprising:
a display panel comprising a display surface defined by a display area configured to display an image and a non-display area adjacent to the display area, and a rear surface opposite the display surface; and
a cover panel attached to the rear surface of the display panel, and comprising:
a light blocking member under the rear surface of the display panel and overlapped by the display area and non-display area of the display panel;
a buffer member under the light blocking member; and
a bridge member in an opening defined by the buffer member, and under the light blocking member, such that the bridge member is adjacent the buffer member,

wherein at least a portion of the bridge member overlaps the display area of the display panel when viewed in a plan view.

17. The portable terminal of claim 16 , further comprising a bracket under the cover panel to support the display panel and the cover panel.

18. The portable terminal of claim 17 , wherein the bridge member is surrounded by the light blocking member, the buffer member, and the bracket.

19. The portable terminal of claim 17 , wherein the cover panel further comprises a heat discharge member overlapped by the buffer member, and located under the buffer member.

20. The portable terminal of claim 19 , wherein the bridge member is in an opening defined by the heat discharge member and connected to the opening of the buffer member.
