Abstract

A flexible display and a method of manufacturing the same are disclosed. In one aspect, the flexible display includes a flexible display panel including an active area displaying configured to display an image and an inactive area extending towards the outside of the active area, and a plurality of wires disposed over the flexible display panel in the inactive area and transmitting configured to transmit an electric signal to the active area. A bending hole is disposed at a corner where two adjacent edges of the flexible display panel meet in the inactive area. The bending hole is interposed between the plurality of the wires and the active area. The corner is folded so as to define a folding region.

First claim

What is claimed is:

1. A flexible display, comprising:
a flexible display panel comprising an active area configured to display an image and an inactive area extending towards the outside of the active area; and
a plurality of wires disposed over the flexible display panel in the inactive area and configured to transmit an electric signal to the active area,
wherein a bending hole is disposed at a corner where two adjacent edges of the flexible display panel meet in the inactive area,
wherein the bending hole is interposed between the plurality of the wires and the active area, and
wherein the corner is folded so as to define a folding region.

2. The flexible display of clam 1 , wherein the bending hole defines a closed curve surrounded by at least one of the edges.

3. The flexible display of claim 2 , wherein the bending hole is surrounded by two adjacent edges.

4. The flexible display of claim 2 , wherein the bending hole includes any one of a triangular shape, a polygonal shape, a circular shape, and an oval shape.

5. The flexible display of claim 1 , wherein at least one bending hole is disposed in the corner.

6. The flexible display of claim 1 , wherein the bending hole does not overlap the wires.

7. The flexible display of claim 1 , wherein the bending hole penetrate through the flexible display panel in a thickness direction thereof.

8. The flexible display of claim 1 , wherein the folding region overlaps the two adjacent edges at the corresponding corner.

9. The flexible display of claim 8 , wherein the wires comprise a plurality of sets of wires and wherein each of the sets of wires extends between two adjacent edges and via the corresponding corner.

10. The flexible display of claim 1 , wherein the edges are folded at least once in a direction opposite to a direction in which the flexible display panel is configured to display an image.

11. The flexible display of claim 1 , wherein the edges are folded to a first surface of the flexible display panel that opposes a second surface of the flexible display panel that is configured to display an image.

12. The flexible display of claim 1 , wherein the edges are folded in a direction opposite to a direction in which the flexible display panel is configured to display an image along a circumference of the active area.

13. The flexible display of claim 1 , wherein a radius of curvature of the flexible display panel is less than or equal to about 1 mm.
