Abstract

A flexible display panel including: a flexible panel including a first region including a display region and oriented on a first plane and a second region including a non-display region and oriented on a second plane different from the first plane; and a flexible encapsulation member disposed on the flexible panel so as to encapsulate at least the display region.

Claims

1. A flexible display panel comprising:

a flexible panel comprising a first region including a display region and oriented on a first plane and a second region including a non-display region and oriented on a second plane different from the first plane; and

a flexible encapsulation member disposed on the flexible panel so as to encapsulate at least the display region.

2. The flexible display panel of claim 1, wherein the display region is configured to be viewed from a first direction in which the first plane is oriented, and the non-display region is configured not to be viewed from the first direction.

3. The flexible display panel of claim 1, wherein an area ratio of the non-display region to the display region visible from a first direction in which the first plane is oriented, is smaller than an area ratio of the non-display region to the display region visible from the first direction than if the non-display region was oriented in the first direction.

4. The flexible display panel of claim 1, wherein a border region having a curvature radius is between the first region and the second region.

5. The flexible display panel of claim 4, wherein the curvature radius has a substantially constant value.

6. The flexible display panel of claim 5, wherein the curvature radius is between about 0.01 mm and about 10 mm.

7. The flexible display panel of claim 6, wherein the curvature radius is between about 0.01 mm and about 1 mm.

8. The flexible display panel of claim 5, wherein a curved surface of the border region is arc-shaped.

9. The flexible display panel of claim 4, wherein the display region extends into the border region.

10. The flexible display panel of claim 4, wherein the non-display region extends into border region.

11. The flexible display panel of claim 4, wherein each of the display region and the non-display region extends into the border region.

12. The flexible display panel of claim 1, wherein the first region is substantially planar.

13. The flexible display panel of claim 1, wherein the second region is substantially planar.

14. The flexible display panel of claim 1, wherein the flexible substrate further comprises a third region extending from an edge of the second region and extending in a direction towards the first region.

15. The flexible display panel of claim 14, wherein the non-display region extends from the second region into the third region.

16. The flexible display panel of claim 15, wherein a pad unit is located in the third region.

17. The flexible display panel of claim 1, further comprising a barrier layer located between the flexible substrate and at least one of the first region and the second region.

18. The flexible display panel of claim 1, further comprising a first protective film located on one side of the flexible panel and a second protective film located on one side of the flexible encapsulation member.

19. The flexible display panel of claim 18, wherein the first protective film and the second protective film are located so as to cover the display region and the non-display region of the flexible panel.

20. The flexible display panel of claim 19, wherein the first protective film and the second protective film are located to be symmetrical to each other.

21. The flexible display panel of claim 18, wherein at least one of the first protective film and the second protective film comprises a polarization film.

22. The flexible display panel of claim 18, wherein the first protective film covers an edge of the flexible panel, and the second protective film covers an edge of the flexible encapsulation member.

23. The flexible display panel of claim 1, wherein the flexible encapsulation member comprises at least one of an inorganic insulating layer and an organic insulating layer.

24. The flexible display panel of claim 1, further comprising a touch panel located on at least one side of the flexible substrate and the flexible encapsulation member and on which an image of the display region is displayed.

25. The flexible display panel of claim 24, wherein the touch panel comprises a flexible film that generally corresponds to a shape of the flexible display panel.

26. The flexible display panel of claim 24, wherein the touch panel comprises a touch region located on the flexible film and generally corresponding to the display region, and a wiring region outside the touch region.

27. A display apparatus comprising a flexible display panel comprising a flexible panel comprising a first region including a display region and oriented on a first plane and a second region including a non-display region and oriented on a second plane different from the first plane, a flexible encapsulation member disposed on the flexible panel so as to encapsulate at least the display region, and a support unit for maintaining a shape of the flexible display panel.

28. The display apparatus of claim 27, wherein the support unit is disposed on the flexible encapsulation member so as to correspond to a shape of the flexible display panel.

29. The display apparatus of claim 27, further comprising a first protective film located on one side of the flexible panel and a second protective film located on one side of the flexible encapsulation member,

wherein the first protective film and the second protective film are located so as to cover the display region and the non-display region of the flexible panel.

30. The display apparatus of claim 27, further comprising a flexible touch panel located on at least one side of the flexible panel and the flexible encapsulation member and on which an image of the display region is displayed, so as to correspond to a shape of the flexible panel.
