Abstract

A display panel is provided, which is capable of removing a Greenish phenomenon by preventing a shift phenomenon arising inside a panel layer by improving conductivity of a component disposed at an upper portion of the panel layer. The display panel can include a cover window, the panel layer disposed below the cover window, and a support member disposed below the panel layer.

First claim

What is claimed is:

1. A display panel comprising:
a cover window;
a panel layer disposed below the cover window; and
a support member disposed below the panel layer,
wherein the support member comprises:
a first adhesive layer;
a first cushion layer disposed below the first adhesive layer;
a conductive tape disposed below the first cushion layer, covered by the first cushion layer and including a conductive material; and
a heat dissipation sheet disposed below the conductive tape and electrically connected with the conductive tape.

2. The display panel according to claim 1 , wherein the first cushion layer comprises a light blocking material.

3. The display panel according to claim 1 , wherein the conductive tape is electrically connected with the heat dissipation sheet by directly contacting with the heat dissipation sheet.

4. The display panel according to claim 1 , further comprising:
a second adhesive layer disposed below the first cushion layer; and
a second cushion layer disposed below the second adhesive layer.

5. The display panel according to claim 1 , wherein the conductive tape further comprises a vertical portion protruding outwards and formed vertically along a side of the first cushion layer.

6. The display panel according to claim 2 , further comprising:
a third adhesive layer disposed below the first cushion layer, covering a bottom portion of the conductive tape and directly contacting with the heat dissipation sheet.

7. The display panel according to claim 6 , wherein the third adhesive layer comprises a conductive material, and
wherein the conductive tape is electrically connected with the heat dissipation sheet through the third adhesive layer.

8. The display panel according to claim 6 , wherein the conductive tape further comprises a vertical portion protruding outwards and formed vertically along a side of the first cushion layer.

9. The display panel according to claim 1 , further comprising:
an adhesive member disposed between the cover window and the panel layer;
a polarizer disposed between the adhesive member and the panel layer; and
a back plate disposed between the panel layer and the first adhesive layer.

10. A display panel comprising:
a cover window;
a panel layer disposed below the cover window; and
a support member disposed below the panel layer,
wherein the support member comprises:
a first adhesive layer;
a first cushion layer disposed below the first adhesive layer;
a conductive tape disposed below the first adhesive layer and comprising a conductive material;
a second adhesive layer disposed below the first cushion layer;
a second cushion layer disposed below the second adhesive layer and the conductive tape, and covering a bottom portion of the conductive tape; and
a heat dissipation sheet disposed below the second cushion layer.

11. The display panel according to claim 10 , wherein the second cushion layer comprises a light blocking material.

12. The display panel according to claim 10 , wherein the second cushion layer comprises a conductive material, and the conductive tape is electrically connected with the heat dissipation sheet through the second cushion layer.

13. The display panel according to claim 12 , wherein the conductive tape further comprises a vertical portion protruding outwards and formed vertically along a side of the panel layer.

14. The display panel according to claim 10 , further comprising:
an adhesive member disposed between the cover window and the panel layer;
a polarizer disposed between the adhesive member and the panel layer; and
a back plate disposed between the panel layer and the first adhesive layer.

15. The display panel according to claim 10 , further comprising a black matrix formed below the cover window and overlapping the conductive tape.
