Abstract
A crystallization apparatus that performs crystallization on a substrate using sequential lateral solidification (SLS) includes a laser generating device for emitting a laser beam, a first telescope lens module and a second telescope lens module at one side of the laser generating device for minimizing a divergent angle of a laser beam emitted by the laser generating device; and a main optical system at one side of the second telescope lens module for uniformizing and amplifying a laser beam transmitted through the second telescope lens module. The main optical system is rotatably formed with respect to the laser generating device.
