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 comprising a substrate, a light emitting element on the substrate, and a sealing layer on the light emitting element;
a light blocking member on a rear surface of the substrate;
a buffer member on a rear surface of the light blocking member and defining an opening on a plane; and
a bridge member on the rear surface of the light blocking member, located in the opening, and non-overlapped with the buffer member in a thickness direction of the display device,
wherein a display area configured to display an image, and a non-display area adjacent to the display area, are defined in the display panel,
wherein the buffer member and the bridge member overlap the display area in the thickness direction, and
wherein the light blocking member overlaps with an entire area of the display area.

2. The display device of claim 1 , wherein each of the opening and the bridge member has a rectangular shape on a plane.

3. The display device of claim 2 , wherein the bridge member comprises first sub-members extending along a first direction and spaced apart in a second direction intersecting the first direction and second sub-members extending along the second direction and spaced apart in the first direction, wherein the first sub-members and the second sub-members are connected to each other and have the rectangular shape on a plane.

4. The display device of claim 1 , wherein the bridge member comprises at least one of a polyethylene terephthalate, a stainless steel, or a resin.

5. The display device of claim 1 , wherein the bridge member comprises an adhesive material, and the bridge member is attached to the light blocking member.

6. The display device of claim 1 , wherein the buffer member comp rises a polymer resin or a sponge formed by foam molding a rubber solution, a urethane-based material, or an acrylic-based material.

7. The display device of claim 1 , wherein a thickness of the buffer member and the thickness of a bridge member are different from each other.

8. The display device of claim 1 , further comprising a light blocking adhesive layer between the display panel and the light blocking member.

9. The display device of claim 1 , further comprising a window member comprising a transmitting area configured to transmit the image provided from the display panel, wherein the display panel disposed between the window member and the light blocking member.

10. A display device comprising:
a display panel comprising a display area configured to display an image and a n on-display area adjacent the display area;
a light blocking member on a rear surface of the display panel;
a first member attached to a rear surface of the light blocking member; and
a second member attached to the rear surface of the light blocking member, wherein the first member is non-overlapped with the second member in a thickness direction of the display device,
wherein the first member and the second member overlap with the display area of the display panel when viewed in the thickness direction,
wherein the light blocking member overlaps with an entire area of the display area, and
wherein an area of the light blocking member is greater than an area of the display area.

11. The display device of claim 10 , wherein the first member has a rectangular shape on a plane, and
wherein the second member comprises a first sub member surrounded by the first member on a plane and a second sub member surrounding the first member on a plane.

12. The display device of claim 10 , wherein the first member comprises an adhesive material, and the second member comprises a polymer resin or a sponge formed by foam molding a rubber solution, a urethane-based material, or an acrylic-based material.

13. The display device of claim 10 , wherein the display panel is an organic light emitting display panel.

14. A display device comprising:
a display panel comprising a display area configured to display an image and a non-display area adjacent the display area;
a light blocking member under the display panel and completely covering the display area of the display panel;
a bridge member under the display area of the display panel and comprising an adhesive material; and
a buffer member under the display area and non-overlapping the bridge member in a thickness direction of the display device,
wherein the display panel displays the image in a direction from a rear surface of the display panel toward an upper surface of the display panel, and the bridge member and the buffer member are spaced apart from the upper surface with the rear surface interposed therebetween.

15. The display device of claim 14 , wherein the light blocking member is between the display panel and the bridge member and is between the display panel and the buffer member.

16. The display device of claim 15 , wherein the light blocking member is a continuous member and the light blocking member overlaps with an entire area of the display area.
