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.

Abstract: An electronic device that includes a display module having an active area that includes at least one pixel and a module hole and a non-active area adjacent to the active area that does not include a pixel. A window is disposed on the display module. A functional layer is disposed between the display module and the window. The functional layer includes a first opening defined therethrough that overlaps with the module hole. A light blocking layer is disposed on at least one of upper and lower surfaces of the functional layer and is positioned adjacent to the first opening. An electronic module is disposed in an opening formed by at least one of the module hole and the first opening.
