Patent ID: 8591280

Claim:
A method of manufacturing an organic light emitting display (OLED) apparatus, the method comprising: forming an active layer on a substrate; forming a gate electrode on the substrate, so as to be insulated from the active layer; forming a first electrode on the substrate, so as to be insulated from the gate electrode and be electrically connected to the active layer, the first electrode having an extended portion that operates as a pixel electrode; forming a second electrode on the substrate, so as to be insulated from the gate electrode and be electrically connected to the active layer; forming a pixel defining layer on the source and drain electrodes, the pixel defining layer having an aperture that exposes the extended portion; forming an intermediate layer comprising an organic light emitting layer, in the aperture and connected to the extended portion; and forming a facing electrode on the intermediate layer, wherein one of the first and second electrodes is a source electrode, and the other is a drain electrode, and wherein the first electrode, the second electrode, and the pixel defining layer are formed using a single halftone mask.
