Abstract: A method for manufacturing a display device includes providing a preliminary display device including a display module, an optical layer disposed on a first surface of the display module, a first protective film disposed on the optical layer, a second protective film disposed on a second surface of the display module, a first adhesive layer disposed between the optical layer and the first protective film, and a second adhesive layer disposed between the second protective film and the display module, forming a mask layer on the first protective film by irradiating a first laser light on the first protective film along a first processing line, and cutting the preliminary display device at an outer periphery of the second processing line by irradiating a second laser light on the first protective film along a second processing line positioned at an outer periphery of the first processing line.
