Abstract: A method of manufacturing an organic light emitting diode display according to an exemplary embodiment of the present invention includes: forming a first electrode on a substrate; forming an insulation layer on the first electrode; etching the insulation layer to expose the first electrode so as to form a pixel defining layer having the same height as the first electrode; forming an organic layer including one or more emission layers on the first electrode of a sub-pixel region defined by the pixel defining layer by applying a laser-induced thermal imaging (LITI) method; and forming a second electrode on the organic layer.
