Abstract:
A method for manufacturing an organic light emitting diode (“OLED”) display which includes first and second pixels each displaying a different color, the method includes: sequentially depositing a first transparent conductive layer and a translucent conductive layer; forming an intermediate first electrode on the second pixel by photolithography and etching of the translucent conductive layer; depositing a second transparent conductive layer on the intermediate first electrode and the first transparent conductive layer; forming a first electrode of the first pixel which includes upper and lower layers on the first pixel and a first electrode of the second pixel which includes a lower first electrode, an intermediate first electrode, and an upper first electrode by photolithography and etching of the second transparent conductive layer and the first transparent conductive layer; forming an emission layer on the first electrodes of the first and second pixels; and forming a second electrode on the emission layer.
