Abstract

A flexible display device including a display panel providing a base surface and a touch screen disposed on the base surface. The display panel may include a plurality of light emitting areas and a non-light emitting area disposed adjacent to the light emitting areas. A plurality of touch electrodes and a plurality of insulating layers of the touch screen may have a mesh shape through which openings corresponding to the plurality of light emitting areas are defined. Accordingly, a flexibility of the flexible display device is improved, and the touch electrode is prevented from being cracked.
