A laser crystallization device is provided, which includes a vibration device vibrating a laser beam along its long axis, wherein a vibration frequency at which the laser beam vibrates is satisfied by Equation 1 below. F<(P*f)/ (2*W) Equation 1 where F is the mirror vibration frequency, W is the laser beam width, P is the laser scan pitch, and f is the laser pulse frequency.
