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: A display device includes a common active pattern, a first gate electrode, and a second gate electrode. The common active pattern includes an NMOS area, a PMOS area, and a silicide area in a same layer as the NMOS area and the PMOS area. The silicide area electrically connects the NMOS area to the PMOS area. The NMOS area includes a first channel area and an n-doped area contacting the first channel area. The PMOS area includes a second channel area and a p-doped area contacting the second channel area. The first gate electrode overlaps the first channel area, and the second gate electrode overlaps the second channel area.

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.
