Abstract

A flexible display is disclosed. In one aspect, the flexible display includes a window layer including a bending area and a non-bending area and a flexible display panel formed over a surface of the window layer and configured to display images. The bending area includes a plurality of cut portions which are configured to be at least partially separated along a plurality of cut lines formed therebetween.

Claims (15)

1. A flexible display, comprising:

a window layer including a bending area and a non-bending area; and

a flexible display panel formed over a surface of the window layer and including a plurality of emission areas through which light emitted from a unit pixel passes to an exterior of the flexible display to display an image,

wherein at least a portion of the window layer is removed from the bending area,

wherein the bending area includes a plurality of protrusions, each arranged at a position corresponding to and overlapping a respective emission area of the plurality of emission areas, wherein each of the protrusions has a greater cross-section in a width direction than that of a corresponding emission area of the plurality of emission areas, the width direction intersecting each of a thickness direction of the window layer and a direction of an axis about which the bending area is bendable, and the flexible display panel further includes a non-display area through which light is not emitted between adjacent emission areas of the respective emission areas,

wherein the bending area further includes a filler formed over the protrusions such that the height of a region of the bending area in which the protrusions are located is substantially equal to that of other regions of the window layer, and

wherein the flexible display further comprises a hard coating layer formed of the same material as the filler and formed over another surface of the window layer so as to oppose the flexible display panel.

2. The flexible display of claim 1 , wherein the filler comprises a transparent synthetic resin or glass.

3. A flexible display, comprising:

a window layer including a bending area and a non-bending area;

a flexible display panel formed over a surface of the window layer and including a plurality of emission areas configured to pass light from a unit pixel therethrough to display an image; and

a hard coating layer formed on another surface of the window layer so as to oppose the flexible display panel,

wherein the bending area includes a plurality of grooves, each arranged at a position corresponding to and overlapping a respective emission area of the plurality of emission areas, wherein each of the grooves has a cross-section in a width direction that is greater than that of a corresponding emission area of the plurality of emission areas, the width direction intersecting each of a thickness direction of the window layer and a direction of an axis about which the bending area is bendable, and the flexible display panel further includes a non-display area through which light is not emitted between adjacent emission areas of the respective emission areas, and

wherein a filler comprising the same material as the hard coating layer fills in the grooves.

4. The flexible display of claim 3 , wherein the hard coating layer is formed of a transparent synthetic resin or glass.
