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.

Laser crystallization apparatus

A laser light source is provided including an airtight container. A first resonance mirror and a second resonance mirror are disposed outside the airtight container. The first resonance mirror includes a lens unit and a reflection coating layer. The lens unit includes a first surface and a second surface, and the first surface is inclined with respect to the second surface.
