Abstract: A method of manufacturing a flexible display panel includes forming a groove in a first area of a layered structure of the flexible display panel, and bending a portion of the first area including the groove from a plane of a second area of the layered structure. The second area extends from the first area. Forming the groove includes radiating a pulsating laser beam along an imaginary line corresponding to the groove such that an overlap ratio between consecutive pulse spots of the pulsating laser beam is greater than or equal to 0.80 and less than or equal to 0.90.

Abstract: A method of manufacturing a display apparatus includes forming a plurality of display units including bending areas on a mother substrate. Each of the plurality of display units include a bending area configured to be bent about a bending axis. A protection film is attached to a lower surface of the mother substrate. The protection film includes a protection film base and an adhesive layer. An opening or a groove is formed corresponding to the bending area of each of the plurality of display units by removing at least a portion of the protection film. The mother substrate and the protection film are cut to separate the plurality of display units from each other. The mother substrate is bent about the bending axis. The removing of the at least a portion of the protection film is performed by a laser beam.

Abstract: A protective film peeling apparatus includes a peeling tape, a tape support portion disposed under one side of the peeling tape, a first pressing portion which is disposed on the one side of the peeling and fixes the one side of the peeling tape to the tape support portion, a second pressing portion which is disposed on another side of the peeling tape and presses and attaches the another side of the peeling tape to one side of a dummy portion of a protective film on a panel, and a grip portion disposed on the dummy portion. The tape support portion and the first pressing portion peel the one side of the dummy portion and a predetermined portion of the dummy portion, and the grip portion peel a remaining portion of the dummy portion.
