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.
