Abstract: A method of manufacturing a display device includes attaching a protective film onto a display panel that includes a display area and a pad area, where the protective film includes an adhesive layer and a protective layer disposed on the adhesive layer, half-cutting the protective film along a cutting line between the display area and the pad area such that a total thickness of the protective layer and a partial thickness of the adhesive layer are cut, irradiating a partially cut portion of the adhesive layer with a laser beam along at least a portion of the cutting line, and detaching a portion of the protective film that corresponds to the pad area along the cutting line.

Abstract: A method for manufacturing a display device includes providing a panel substrate including a panel area, a peripheral area, and a dummy pattern disposed at a boundary between the panel area and the peripheral area. A protection part is disposed on the panel substrate. A first processing line overlaps a first outline of the panel area extending from a first point of an outline of the panel area. A second processing line overlaps a second outline extending from the first point in a direction different from the first outline are defined. The protection part is partially cut along the first processing line. The protection part is fully cut along the second processing line. The dummy pattern overlaps the first point.
