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.
Claims4
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.
