Abstract: A laser crystallization apparatus includes a plurality of laser generators which generate a plurality of laser beams, a plurality of attenuators which adjust energy intensity of the plurality of laser generators, and an optical module which overlap outputs of the plurality of attenuators to output a line beam. A first attenuator of the plurality of attenuators attenuates the energy intensity of the corresponding laser beam, and a second attenuator of the plurality of attenuators maintains the energy intensity of the corresponding laser beam.
