Abstract: Disclosed is a display device that includes a substrate having an active area and a dead area around the active area; an alignment mark on the inside surface of the substrate in a part of the dead area; and a light-shielding pattern on a rear surface of the substrate in the dead area, the light-shielding pattern including a mark hole for exposing the alignment mark. By providing the light-shielding pattern on a display surface in the dead area, the display device has expanded active display area and improved visual appreciation.
