Abstract

A flexible display panel includes a flexible substrate including a first region including a display region and having a curved display surface, and a plurality of non-display regions that is located outside the display region and including a second region located outside the first region and folded in a direction different from a display direction of the first region, and an encapsulation member for encapsulating the display region along the curved display surface.

Claims (47)

1. A display apparatus comprising:

a flexible display panel comprising:

a flexible substrate;

a display region comprising a first light-emitting device and disposed on a first side of the flexible substrate;

a first flexible non-display region disposed on the first side of the flexible substrate and disposed outside the display region;

a border region disposed between the display region and the first flexible non-display region, the border region comprising a second light-emitting device and having a curvature radius;

a second flexible non-display region disposed on the first side of the flexible substrate and disposed outside the first flexible non-display region, the second flexible non-display region overlapping the display region;

an encapsulation member encapsulating the display region, the border region, and at least one of the first and second flexible non-display regions;

a touch layer disposed on the encapsulation member and comprising a touch region and a touch wiring outside the touch region, the touch region overlapping the display region, and the border region and the touch wiring overlapping the first and second flexible non-display regions; and

a pad unit in the second flexible non-display region on the first side of the flexible substrate, the pad unit overlapping the display region,

a transparent protection window disposed on the touch layer; and

an adhesive layer disposed between the touch layer and the transparent protection window.

2. The display apparatus of claim 1 ,

wherein the display region and the border region are connected without a boundary.

3. The display apparatus of claim 1 , wherein the first and second light-emitting devices of the display region and the border region comprise a first electrode, a second electrode, and an organic light-emitting layer between the first electrode and the second electrode.

4. The display apparatus of claim 2 , wherein the border region has a constant curvature radius.

5. The display apparatus of claim 4 , wherein the border region has a convex display surface.

6. The display apparatus of claim 1 , wherein the display region has a constant curvature radius.

7. The display apparatus of claim 6 , wherein the display region has a concave display surface.

8. The display apparatus of claim 1 , wherein the encapsulation member comprises an organic layer and an inorganic layer.

9. The display apparatus of claim 1 , further comprising a connector coupled with the pad unit,

wherein the display region overlaps the pad unit and the connector.

10. A display apparatus comprising:

a flexible display panel comprising:

a flexible substrate;

a barrier layer on the flexible substrate;

a display region disposed on a first side of the barrier layer;

a first flexible non-display region disposed on the first side of the barrier layer and disposed outside the display region;

a second flexible non-display region disposed on the first side of the barrier layer and disposed outside the first flexible non-display region, the second flexible non-display region overlapping the display region;

an encapsulation member encapsulating the display region and at least one of the first and second flexible non-display regions;

a touch layer disposed on the encapsulation member and comprising a touch region and a touch wiring outside the touch region, the touch region overlapping the display region, and the touch wiring overlapping the first and second non-display regions; and

a pad unit in the second flexible non-display region on the first side of the barrier layer, the pad unit overlapping the display region,

a transparent protection window disposed on the touch layer; and

an adhesive layer disposed between the touch layer and the transparent protection window.

11. The display apparatus of claim 10 , further comprising:

a border region disposed between the display region and the first flexible non-display region, the border region displaying an image.

12. The display apparatus of claim 11 , wherein the border region comprises at least one light-emitting device.

13. The display apparatus of claim 12 , wherein the light-emitting device comprises a first electrode, a second electrode, and an organic light-emitting layer between the first electrode and the second electrode.

14. The display apparatus of claim 11 , wherein the border region has a constant curvature radius.

15. The display apparatus of claim 14 , wherein the border region has a convex display surface.

16. The display apparatus of claim 10 , wherein the display region has a constant curvature radius.

17. The display apparatus of claim 16 , wherein the display region has a concave display surface.

18. The display apparatus of claim 10 , wherein the display region comprises at least one light-emitting device.

19. The display apparatus of claim 18 , wherein the light-emitting device comprises a first electrode, a second electrode, and an organic light-emitting layer between the first electrode and the second electrode.

20. The display apparatus of claim 10 , wherein the encapsulation member comprises an organic layer and an inorganic layer.

21. The display apparatus of claim 10 , further comprising a connector coupled with the pad unit,

wherein the display region overlaps the pad unit and the connector.
