The FFS includes a first surface and a second surface opposite the first surface. The second surface includes, in the peripheral region, a cavity extending into the FFS. The DC is on the first surface and includes at least one transistor. The CP is in the cavity and is partially exposed by the cavity. The conductive line electrically connects the CP to the DC. The light-emitting device is in the display region and is electrically connected to the DC. The support substrate is on the second surface. In a view normal to the second surface, the support substrate is spaced apart from the CP.

Abstract: A laser polycrystallization apparatus including: a light source for emitting a laser beam; a diffraction grating for receiving the laser beam from the light source, changing a path and a magnitude of the received laser beam, and outputting the changed laser beam; a light split portion for splitting the laser beam received from the diffraction grating; and a light superposition portion for superposing the split laser beams received from the light split portion and irradiating the superposed split laser beams to a substrate. An angle between the laser beam irradiated to an incidence surface of the diffraction grating from the light source and a line substantially perpendicular to an emission surface of the diffraction grating is an acute angle.

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.
