Abstract: A method for manufacturing a display device is provided. A process of forming an inspection pattern, in which a protective film unit is partially removed in a thickness direction, in a pad area portion of the protective film unit, which corresponds to a pad area of a display unit, may be performed, and then, a process of delaminating the pad area portion of the protective film unit may be performed. A process of checking whether the inspection pattern exists may be performed to check whether the delamination has succeeded, and, at the same time, a process of measuring distances from an alignment mark to each of a long side and a short side of the display unit may be performed.

Abstract: A manufacturing apparatus of a display device includes: a first stage including a plurality of cell units, each including: a display unit including a display area, and a pad area; and a protective film unit attached to the display unit, and including a display film portion corresponding to the display area, and a pad film portion corresponding to the pad area; a second stage; and a transfer unit to transfer the cell units to the second stage from the first stage, and to peel off the pad film portion. The transfer unit includes: a body member; a plurality of pins along a first direction on a first surface of the body member; a plurality of suction pads on the first surface of the body member along a second direction; and a reel member on a second surface of the body member to supply a peeling tape to the second surface.
