A display device includes: a flexible substrate; a plurality of conductive lines on the flexible substrate; a thin film transistor connected to the plurality of conductive lines; and an organic light emitting element connected to the thin film transistor. As a curvature of an area of the flexible substrate increases, a width or a thickness of each of the conductive lines increases.

Flexible display device having reduced strain during bending or rolling

A flexible display device includes: a bendable display panel; a protective layer on a surface of the display panel; and an elastic layer on the first surface of the protective layer. The protective layer has a groove in a first surface thereof, and the elastic layer is in the groove in the protective layer.

Flexible display device

A rollable display device includes: a window member; a first pressure sensitive adhesive member arranged under the window member; a display module detachable from and attachable to the window member by the first pressure sensitive adhesive member; a housing having a groove through which the window member, the first pressure sensitive adhesive member, and the display module are configured to enter and exit from the housing; a first rotation member on which the window member and the first pressure sensitive adhesive member are rollable or slidable; and a second rotation member on which the display module is rollable or slidable.

Rollable display device

A flexible display and method of manufacturing the same are disclosed. In one aspect, the method includes forming a metal peroxide layer over a supporting substrate, forming a metal layer over the metal peroxide layer and forming a flexible substrate over the metal layer. The method also includes forming a display layer over the flexible substrate, irradiating the supporting substrate with laser light in a direction from the supporting substrate to the flexible substrate so as to form a metal oxide layer and separating the supporting substrate from the flexible substrate with the metal oxide layer as a boundary between the supporting substrate and the flexible substrate.

Method of manufacturing flexible display

Provided is a method of manufacturing a flexible display apparatus, the method including forming a sacrificial layer on a support substrate; forming a first material layer having a higher hydrogen concentration than the sacrificial layer on the sacrificial layer; forming a second material layer, preventing hydrogen diffusion from the first material layer to a flexible substrate, on the first material layer; forming the flexible substrate on the second material layer; forming a display layer on the flexible substrate; and irradiating a laser onto the support substrate to delaminate the sacrificial layer from the first material layer.
