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.

Abstract: Disclosed is a method for forming a display device. The method includes forming an alignment mark on a front surface of a substrate having a display region and a non-display region surrounding the display region, forming an alignment protection pattern on a rear surface of the substrate such that the alignment protection pattern overlaps the alignment mark, and forming a light-shielding member in the non-display region on the rear surface of the substrate such that the light-shielding member forms a boundary with the alignment protection pattern.
