A method of manufacturing an organic light emitting diode display includes forming a plurality of signal lines and a plurality of TFTs on a substrate, forming a passivation layer on the signal lines and the TFTs, forming a photosensitive layer having a plurality of openings on the passivation layer, etching the passivation layer using the photosensitive layer as a mask, forming a first electrode by depositing and etching a conductive layer on substantially the entire surface including the photosensitive layer, forming a light emitting member in portions of the openings, and forming a second electrode on the light emitting member and the photosensitive layer.
