An apparatus for manufacturing a display device includes: a support to mount a display substrate having a pixel area; a multi-layered film disposed above the display substrate and including a light-transmissive base layer and a source layer disposed on the base layer facing the pixel area and including an organic material; and a laser device spaced apart from the multi-layered film to radiate a laser beam toward the multi-layered film. The source layer is capable of absorbing the laser beam.
