Organic light emitting display apparatus and method of manufacturing organic light emitting display apparatus

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 upper surfaces of the first electrode and the second electrode such that the pixel defining layer does not directly contact side surfaces of the first electrode and the second electrode, 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.
