Patent ID: 8455792

Claim:
A laser irradiation apparatus for bonding a first substrate and a second substrate of a display device by melting a plurality of bonding members disposed between the first and second substrates to define cells when the display device is manufactured, the display device including light emitting elements disposed on a surface of the first substrate such that the bonding members respectively encompass lateral regions of the light emitting elements, the laser irradiation apparatus comprising: a stage on which the first substrate is mounted; a laser oscillation member configured to irradiate a laser beam that melts the bonding members disposed between the first substrate and the second substrate; a scanner configured to irradiate the laser beam incident from the laser oscillation member onto the bonding members, the scanner including a plurality of reflectors, and the scanner being configured to sequentially irradiate the laser beam on portions of the bonding members; and a beam blocking member between the laser oscillation member and the scanner, the beam blocking member being configured to intermittently block transmission of the laser beam to the scanner.
