<p>A laser irradiation device comprises light sources, a laser thermal transfer mask, and a stage. The light sources irradiate laser beam to have regular output energy. The laser thermal transfer mask is arranged on the bottom of the light sources. The stage is arranged on the bottom of the laser thermal transfer mask and seats an acceptor substrate having a pixel area. The laser thermal transfer mask comprises a transmission unit and a shielding unit. The transmission unit has an opening consisting of a plurality of slits, which laser beam passes through, and corresponds to the pixel area. The shielding unit reflects and blocks the laser beam. The laser irradiation device controls output energy of laser beam which penetrates the laser thermal transfer mask as a square wave form.</p> |
