Abstract

A flexible display device including a display panel providing a base surface and a touch screen disposed on the base surface. The display panel may include a plurality of light emitting areas and a non-light emitting area disposed adjacent to the light emitting areas. A plurality of touch electrodes and a plurality of insulating layers of the touch screen may have a mesh shape through which openings corresponding to the plurality of light emitting areas are defined. Accordingly, a flexibility of the flexible display device is improved, and the touch electrode is prevented from being cracked.

First claim

a plurality of conductive patterns disposed on the first insulating layer and overlapped with a portion of the shielding layer; and
a second insulating layer disposed on the first insulating layer.

2. The flexible display device of claim 1 , wherein the first insulating layer comprises a first over coating layer providing a first surface on which the plurality of conductive patterns are disposed.

3. The flexible display device of claim 2 , wherein the second insulating layer comprises a plurality of color filters, each being overlapped with a corresponding light emitting area among the plurality of light emitting areas.

4. The flexible display device of claim 3 , wherein an edge of each of the plurality of color filters is overlapped with the non-light emitting area.

5. The flexible display device of claim 4 , wherein the second insulating layer further comprises a second over coating layer covering the plurality of color filters.

6. The flexible display device of claim 4 , wherein the second insulating layer further comprises a black matrix disposed on the first surface, covering the plurality of conductive patterns, and comprising a plurality of openings defined to correspond to the plurality of light emitting areas.

7. The flexible display device of claim 1 , further comprising a black matrix disposed on the second insulating layer and comprising a plurality of openings defined to correspond to the plurality of light emitting areas.

8. The flexible display device of claim 1 , wherein the first insulating layer comprises a plurality of color filters each being overlapped with a corresponding light emitting area among the plurality of light emitting areas.

9. The flexible display device of claim 8 , wherein the second insulating layer comprises an over coating layer.

10. The flexible display device of claim 9 , wherein the second insulating layer further comprises a black matrix disposed on the plurality of color filters, covering the first conductive patterns, and comprising openings defined therethrough to correspond to the plurality of light emitting areas, and the over coating layer covers the black matrix.

11. The flexible display device of claim 1 , wherein at least one of the first and second insulating layers comprises a hard coating layer.

12. The flexible display device of claim 1 , wherein the shielding layer comprises a plurality of first mesh lines to define a plurality of first openings corresponding to the plurality of light emitting areas, the plurality of first conductive patterns comprise a plurality of second mesh lines to define a plurality of second openings corresponding to the plurality of light emitting areas, and the plurality of first mesh lines have a line width greater than a line width of the plurality of second mesh lines.

13. The flexible display device of claim 1 , further comprising a window member disposed on the display panel,
wherein the window member comprises a base member and a hard coating layer disposed on the base member.

14. The flexible display device of claim 1 , wherein the shielding layer receives a ground voltage.

15. The flexible display device of claim 1 , wherein the display panel comprises:
a base substrate;
a circuit layer disposed on the base substrate;
an organic light emitting device layer disposed on the circuit layer; and
a thin film encapsulation layer encapsulating the organic light emitting device layer.

16. The flexible display device of claim 15 , wherein the thin film encapsulation layer provides the base surface.

17. A flexible display device, comprising:
a display panel having a base surface and comprising a plurality of light emitting areas and a non-light emitting area disposed adjacent to the plurality of light emitting areas;
a conductive layer disposed on the base surface and overlapped with the non-light emitting area;
a first insulating layer disposed on the base surface and covering the conductive layer;
a plurality of conductive patterns disposed on the first insulating layer and overlapped with a portion of the conductive layer; and
a second insulating layer disposed on the first insulating layer,
wherein one of the first insulating layer and the second insulating layer includes a plurality of color filters each being overlapped with a corresponding light emitting area among the plurality of light emitting areas.

18. The flexible display device of claim 17 , further comprising a black matrix disposed on the second insulating layer and comprising a plurality of openings defined to correspond to the plurality of light emitting areas.
