Abstract

A display device includes a flexible substrate including a display area and a non-display area. The substrate has a first surface and a second surface opposite to the first surface. A first protection film is disposed on the first surface of the substrate. The first protection film is disposed over the display area of the substrate. A second protection film is disposed on the first surface of the substrate. The second protection film is disposed over the non-display area of the substrate. A light transmittance of the first protection film is higher than that of the second protection film.
