Abstract: A display apparatus including a substrate having a display area in which a display device is provided to display an image, and a non-display area around the display area. The non-display area includes a bending area that is bent about a bending axis; an encapsulation layer arranged above the display area; a touch electrode arranged above the encapsulation layer; a touch wire connected to the touch electrode and extending to the non-display area; and a fan-out wiring connected to a signal wiring that applies electric signals to the display area. At least a portion of the fan-out wiring is arranged in the bending area, and the fan-out wiring includes the same material as the touch wire.

Abstract: A flexible display device includes a protection member, a first adhesion member, a display member, a second adhesion member, and a window member. A thickness of the display member is less than a sum of thicknesses of the protection member and the window member. The display member includes a display panel layer, a touch sensing layer, and a reflection prevention layer integrated with each other to reduce a thickness of the flexible display device. The reduction in thickness enables the flexible display device to be bent with a relatively small radius of curvature, as well as to be repeatedly bent (or otherwise flexed) with reduced potential for delamination of the first and second adhesion members.
