Abstract

A flexible display device including a display panel layer, a touch sensing layer, a reflection prevention layer, and a window layer. The touch sensing layer is disposed directly on a first display panel surface, a second display panel surface facing the first display panel surface in a thickness direction, or a second base surface of the reflection prevention layer. The reflection prevention layer is disposed directly on the second display panel surface or a first base surface of the touch sensing layer. The window layer is disposed directly on the first base surface or the second base surface.

Claims (60)

1. A display device, comprising:

a base layer;

a first organic light emitting element on the base layer;

a second organic light emitting element on the base layer;

a first black matrix on the first and second organic light emitting elements and having a first transmission opening corresponding to the first organic light emitting element and a second transmission opening corresponding to the second organic light emitting element;

a first color filter on the first organic light emitting element and in the first transmission opening;

a second color filter on the second organic light emitting element and in the second transmission opening; and

a second black matrix on the first and second first color filters and overlapping with the first black matrix,

wherein:

a portion of the first color filter is disposed on the first black matrix;

a portion of the second color filter is disposed on the first black matrix;

a first portion of the second black matrix is disposed on the portion of the first color filter and a second portion of the second black matrix is disposed on the portion of the second color filter;

the portion of the first color filter is disposed between the first black matrix and the first portion of the second black matrix; and

the portion of the second color filter is disposed between the first black matrix and the second portion of the second black matrix.

2. The display device of claim 1 , further comprising a pixel defining layer, wherein:

each of the first and second organic light emitting elements comprises a first electrode, an organic light emitting layer on the first electrode, and a second electrode on the organic light emitting layer; and

the pixel defining layer has a first opening exposing the first electrode of the first organic light emitting element and a second opening exposing the first electrode of the second organic light emitting element.

3. The display device of claim 2 , wherein:

the first opening overlaps with the first transmission opening; and

the first opening is disposed inside the first transmission opening on a plane.

4. The display device of claim 1 , further comprising a thin film encapsulation layer encapsulating the first and second organic light emitting elements.

5. The display device of claim 4 , wherein the first black matrix contacts the thin film encapsulation layer.

6. The display device of claim 4 , further comprising a plurality of conductive patterns overlapping with the first black matrix and disposed on the thin film encapsulation layer.

7. The display device of claim 6 , wherein the plurality of conductive patterns contacts the first black matrix or the second black matrix.

8. The display device of claim 1 , wherein the first color filter has a thickness greater than a thickness of the first black matrix.

9. The display device of claim 1 , wherein a boundary between the first color filter and the second color filter overlaps the first black matrix.

10. The display device of claim 1 , further comprising a protection layer including an organic material.

11. The display device of claim 1 , wherein each of the first and second color filters contacts the first black matrix.

12. The display device of claim 11 , wherein the second black matrix contacts each of the first and second color filters.

13. An electronic device, comprising:

a display device, wherein the display device comprises:

a base layer;

a first portion of the second black matrix is disposed on the portion of the first color filter and a second portion of the second black matrix is disposed on the portion of the second color filter;

the portion of the first color filter is disposed between the first black matrix and the first portion of the second black matrix; and

the portion of the second color filter is disposed between the first black matrix and the second portion of the second black matrix.

14. The electronic device of claim 13 , wherein the display device further comprises:

each of the first and second organic light emitting elements comprises a first electrode, an organic light emitting layer on the first electrode, and a second electrode on the organic light emitting layer; and

the pixel defining layer has a first opening exposing the first electrode of the first organic light emitting element and a second opening exposing the first electrode of the second organic light emitting element.

15. The electronic device of claim 14 , wherein:

the first opening overlaps with the first transmission opening; and

the first opening is disposed inside the first transmission opening on a plane.

16. The electronic device of claim 13 , wherein the display device further comprises a thin film encapsulation layer encapsulating the first and second organic light emitting elements.

17. The electronic device of claim 16 , wherein the first black matrix contacts the thin film encapsulation layer.

18. The electronic device of claim 16 , wherein the display device further comprises a plurality of conductive patterns overlapping with the first black matrix and disposed on the thin film encapsulation layer.

19. The electronic device of claim 18 , wherein the plurality of conductive patterns contacts the first black matrix or the second black matrix.

20. The electronic device of claim 13 , wherein the first color filter has a thickness greater than a thickness of the first black matrix.

21. The electronic device of claim 13 , wherein a boundary between the first color filter and the second color filter overlaps the first black matrix.

22. The electronic device of claim 13 , wherein the display device further comprises a protection layer including an organic material.

23. The electronic device of claim 13 , wherein each of the first and second color filters contacts the first black matrix.

24. The electronic device of claim 23 , wherein the second black matrix contacts each of the first and second color filters.
