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.
