Abstract: A laser device includes a light source generating a laser beam, a stage, and a lens assembly disposed between the light source and the stage and irradiating the laser beam to a substrate disposed on the stage. The lens assembly includes a first lens assembly making divergent the laser beam provided from the light source, a deflector changing a path of the laser beam provided from the first lens assembly, and a second lens assembly condensing the laser beam provided from the deflector and irradiating the condensed laser beam to the substrate.
