Abstract: An apparatus for manufacturing a display apparatus includes a chamber in which a loading area is defined, a stage unit disposed in the loading area, where the stage unit fixes a fixing surface of a target, an optical unit disposed outside the chamber, where the optical unit processes a processing surface of the target. The optical unit includes a laser radiating unit which radiates a laser toward the processing surface of the target and a laser moving unit which moves the laser radiating unit along a processing path in a plan view.
