Abstract

A display device includes a display panel having a display area and a non-display area, the non-display area being disposed at a peripheral portion of the display area and having a bending area; an integrated circuit (IC) disposed in the non-display area to drive the display panel; a first layer formed between the display area and the IC and covering the bending area; and a first member covering the IC and the first layer and overlapping with the bending area.

Claims (45)

1. A display device comprising:

a display panel having a display area and a non-display area, the non-display area being disposed at a peripheral portion of the display area and having a bending area;

an integrated circuit (IC) disposed in the non-display area to drive the display panel;

a first layer formed between the display area and the IC and covering the bending area;

a first member covering the IC and the first layer and overlapping with the bending area;

an output pad unit disposed on an outer side of the IC in the non-display area; and

a ground electrode disposed on a flexible printed circuit board;

wherein the flexible printed circuit board electrically connected to the output pad unit, the first member is connected to the ground electrode to reduce interference from static electricity or electromagnetic waves in the non-display area.

2. The display device of claim 1 , wherein the first member comprises a first cover member having a first insulating layer, a conductive layer disposed on the first insulating layer, a second insulating layer disposed on the conductive layer, and having an opening exposing a part of the conductive layer through the first insulating layer, and

wherein the conductive layer comes in contact with the ground electrode via the opening.

3. The display device of claim 1 , further comprising:

a polarization layer disposed on the display panel; a first adhesive layer disposed on the polarization layer; and

a cover window disposed on the first adhesive layer.

4. The display device of claim 3 , wherein a part of the first member contacts the first adhesive layer, a part of the first member is disposed between the first adhesive layer and the first layer, and the first layer and the first member abut the polarization layer.

5. The display device of claim 1 , further comprising: a support panel disposed between the display area and the drive IC, and wherein the first layer comprises a protective layer and the first member comprises a first cover member.

6. The display device of claim 1 , wherein the IC completely overlaps the first member.

7. The display device of claim 1 , further comprising: a second member disposed on the display panel and overlapping with the bending area.

8. A display device comprising:

a display panel having a display area and a non-display area, the non-display area being disposed at a peripheral portion of the display area and having a bending area;

an integrated circuit (IC) disposed in the non-display area to drive the display panel;

a first layer formed between the display area and the IC and covering the bending area; and

a first member covering the IC and the first layer and overlapping with the bending area,

wherein the first member comprises a first insulating layer, a conductive layer disposed on the first insulating layer, and a second insulating layer disposed on the conductive layer.

9. The display device of claim 8 , wherein the first insulating layer abuts the IC.

10. The display device of claim 8 , wherein the first insulating layer comprises a first non-conductive adhesive layer, the conductive layer comprises a conductive adhesive layer, and the second insulating layer comprises a second non-conductive adhesive layer.

11. A display device comprising:

a display panel having a display area and a non-display area, the non-display area being disposed at a peripheral portion of the display area and having a bending area;

a integrated circuit (IC) disposed in the non-display area to drive the display panel;

a first layer formed between the display area and the IC and covering the bending area;

a first member covering the IC and a protective layer and overlapping with the bending area, and comprises a conductive member to reduce interference from static electricity or electromagnetic waves in the non-display area; and

a ground electrode disposed on a flexible printed circuit board;

wherein the conductive member is connected to the ground electrode.

12. A method for manufacturing a display device, the method comprising the steps of:

preparing a display panel having a display area and a non-display area, the non-display area being disposed at a peripheral portion of the display area and having an integrated circuit (IC) therein;

forming a protective layer between the IC and the display area;

forming a first member to cover the drive IC and the protective layer;

bending the display panel to form a bending area between the drive IC and the display area;

connecting a flexible printed circuit board to the non-display area;

forming a ground electrode on the flexible printed circuit board; and

connecting the first member to the ground electrode.

13. The method of claim 12 , further comprising the step of:

disposing a second member on a the display panel.

14. The method of claim 12 , wherein the first member further comprises a first cover member that partially covers the flexible printed circuit board.

15. The method of claim 12 , wherein the first cover member comprises a first insulating layer, a conductive layer and a second insulating layer stacked on one another, and

wherein the step of connecting the first cover member to the ground electrode comprises recessing the first insulating layer to form an opening via which the conductive layer is exposed, and electrically connecting a part of the conductive layer exposed via the opening with the ground electrode.
