Abstract

A display panel includes a cover window; an adhesion layer below the cover window; a polarizing plate below the adhesion layer; a panel layer below the polarizing plate; a support member below the panel layer; and a conductive side cover attached to a side surface of the polarizing plate and to a lower surface of the support member, wherein at least one of the cover window, the adhesion layer, and the polarizing plate includes an electrically conductive material to have increased electrical conductivity.

First claim

What is claimed is:

1. A display panel, comprising:
a cover window;
an adhesion layer below the cover window;
a polarizing plate below the adhesion layer;
a panel layer below the polarizing plate;
a support member below the panel layer; and
a conductive side cover attached to a side surface of the polarizing plate and to a lower surface of the support member, the conductive side cover including a fixing portion protruding in a direction inward from the side surface such that the fixing portion is disposed under and in direct contact with a portion of the adhesion layer,
wherein at least one of the cover window, the adhesion layer, and the polarizing plate includes an electrically conductive material to have increased electrical conductivity.

2. The display panel of claim 1 , wherein an electrical path is defined such that the cover window is electrically connected to the support member through the conductive side cover and the at least one of the cover window, the adhesion layer and the polarizing plate.

3. The display panel of claim 2 , wherein the conductive side cover includes a metal.

4. The display panel of claim 3 , wherein the metal includes silver (Ag).

5. The display panel of claim 1 , wherein the conductive side cover is covered by a black matrix.

6. The display panel of claim 1 , wherein the polarizing plate includes a conductive coating layer disposed thereon.

7. The display panel of claim 6 , wherein the fixing portion is on the conductive coating layer.

8. The display panel of claim 6 , wherein the conductive coating layer includes a stepped portion, and
wherein the fixing portion is in direct contact with the stepped portion.

9. The display panel of claim 1 , wherein the adhesion layer includes a conductive particle therein.

10. The display panel of claim 9 , wherein the fixing portion is in direct contact with an upper surface of the polarizing plate.

11. The display panel of claim 9 , wherein the polarizing plate includes a stepped portion, and wherein the fixing portion is in direct contact with the stepped portion.

12. The display panel of claim 1 , wherein the cover window includes a conductive coating layer disposed therebelow.

13. The display panel of claim 12 , wherein the conductive side cover includes an extending portion below the conductive coating layer and protruding outward, and wherein the extending portion is on a side surface of the adhesion layer.

14. The display panel of claim 1 , further comprising a back plate disposed between the panel layer and the support member.

15. The display panel of claim 1 , wherein the support member includes an adhesive, a cushion tape, and a heat dissipation sheet sequentially disposed below the panel layer.

16. The display panel of claim 1 , wherein the ends of the polarizing plate and the panel layer extend further in a horizontal direction than an end of the support member.

17. The display panel of claim 16 , wherein the conductive side cover includes a bent shape to abut the ends of the polarizing plate and the end of the support member.

18. The display panel of claim 17 , wherein a first end of the conductive side cover extends in the horizontal direction to be disposed between the cover window and the polarizing plate.

19. The display panel of claim 17 , wherein a second end of the conductive side cover extends in the horizontal direction along the lower surface of the support member.

20. The display panel of claim 17 , wherein a first end of the conductive side cover extends in the horizontal direction to be protruding away from the polarizing plate and to be disposed below the cover window.

21. The display panel of claim 1 , wherein the support member includes an adhesive, a cushion tape, and a heat dissipation sheet sequentially below the panel layer, and
wherein a second end of the conductive side cover extends in the horizontal direction along the lower surface of the heat dissipation sheet of the support member.

22. A display panel, comprising:
a cover window;
an adhesion layer below the cover window;
a polarizing plate below the adhesion layer;
a panel layer below the polarizing plate;
a support member below the panel layer; and
a conductive side cover attached to a side surface of the polarizing plate and to a lower surface of the support member,
wherein the polarizing plate includes a conductive coating layer disposed thereon, and
wherein at least one of the cover window, the adhesion layer, and the polarizing plate includes an electrically conductive material to have increased electrical conductivity.

23. A display panel, comprising:
a cover window;
an adhesion layer below the cover window;
a polarizing plate below the adhesion layer;
a panel layer below the polarizing plate;
a support member below the panel layer; and
a conductive side cover attached to a side surface of the polarizing plate and to a lower surface of the support member,
wherein at least one of the cover window, the adhesion layer, and the polarizing plate includes an electrically conductive material to have increased electrical conductivity
wherein the adhesion layer includes a conductive particle therein,
wherein the polarizing plate includes a stepped portion, and
wherein the conductive side cover includes a fixing portion protruding inward to be in direct contact with the adhesion layer and the stepped portion of the polarizing plate.

24. A display panel, comprising:
a cover window;
an adhesion layer below the cover window;
a polarizing plate below the adhesion layer;
a panel layer below the polarizing plate;
a support member below the panel layer; and
a conductive side cover attached to a side surface of the polarizing plate and to a lower surface of the support member,
wherein the support member includes an adhesive, a cushion tape, and a heat dissipation sheet sequentially disposed below the panel layer, and
wherein at least one of the cover window, the adhesion layer, and the polarizing plate includes an electrically conductive material to have increased electrical conductivity.
