Abstract: A flexible display apparatus includes a substrate having a bending portion, a display over the substrate, and a cover over the substrate and covering the display. The cover includes a first film having a first surface and a second surface opposite the first surface, a second film over the first film, and an adhesive layer between the first film and the second film and attaching the first film to the second film. The first film includes at least one division line in at least some regions thereof in a direction from the first surface toward the second surface.

Abstract: A flexible display window includes a flexible base layer including a flexible resin, a first silica nano particle coating layer including full-type silica nano particles, where the first silica nano particle coating layer is disposed on the flexible base layer, a flexible hard coating layer including a flexible hard coating resin, where the flexible hard coating layer is disposed on the first silica nano particle coating layer, and a second silica nano particle coating layer including hollow-type silica nano particles, where the second silica nano particle coating layer is disposed on the flexible hard coating layer. Thus, the flexible display window can enhance impact-resistance of a flexible display while reducing reflectivity of the flexible display.
