Abstract: A method of manufacturing an organic light-emitting apparatus includes: disposing a pixel electrode on a substrate in a display region; disposing a pixel defining layer covering the pixel electrode; exposing the pixel electrode by forming an opening in the pixel defining layer; and ashing residue of the pixel defining layer by using a laser, the residue remaining on the exposed pixel electrode in the opening.
