Abstract
A laser crystallization apparatus according to an embodiment includes: a light source unit which irradiates a laser beam; and a path conversion unit which converts the laser beam incident from the light source unit into a linear beam having a long axis parallel to a first direction and a short axis parallel to a second direction. The linear beam propagates in a third direction perpendicular to the first direction and the second direction, the path conversion unit includes an incident window extending parallel to a first length direction, an emission window extending parallel to a second direction, a first reflection unit disposed at the same side with the incident window, and a second reflection unit disposed at the same side with the emission window, and the second length direction extends parallel to the first direction in a view of the third direction.
