Abstract: An apparatus for manufacturing a display device and a method for manufacturing a display device are provided. An embodiment of an apparatus for manufacturing a display device includes a laser module configured to emit a laser beam and a first optical system disposed on one side of the laser module such that the laser beam is provided to the first optical system, wherein the first optical system controls an energy profile of the laser beam, wherein, on a first irradiation surface positioned at one side in a traveling direction of the laser beam from a focal point of the laser beam, the energy profile of the laser beam includes a first increase and then a first decrease in energy along a line parallel to the first irradiation surface from an outer perimeter of the laser beam toward a center of the laser beam, and wherein the energy profile of the laser beam includes a first peak corresponding to where the energy begins to decrease.

Abstract: A display device including a substrate and a stacked structure on the substrate. The substrate has a first hole, and the stacked structure has a second hole. The second hole partially overlaps the first hole and has an edge outside the first hole in a plan view. The substrate has a substrate exposed portion exposed to the second hole, and the substrate exposed portion is partially depressed in an edge direction of the second hole.
