Abstract

A laser processing apparatus includes: a laser generator that generates a laser beam, a diffractive optical element that divides the laser beam generated by the laser generator into a plurality of sub-laser beams, and a beam gap adjustor that adjusts a gap between neighboring ones of the plurality of sub-laser beams. Therefore, by installing a diffractive optical element that divides a laser beam that is generated by the laser generator into the plurality of sub-laser beams and a beam gap adjustor to adjust a gap between a plurality of sub-laser beams, the laser processing apparatus can form a processing pattern of various resolutions in a shadow mask while improving a processing speed of the shadow mask.
