Claim:
1. A method of manufacturing an organic light emitting display apparatus, the method comprising: forming a pixel electrode and a bus electrode on a same layer to be spaced apart and electrically insulated from each other; forming a pixel defining layer on the same layer so at least a part of the pixel electrode including a central part thereof and at least a part of the bus electrode are exposed; forming a first intermediate layer on a top surface of the pixel defining layer between the pixel electrode and the bus electrode, on the pixel electrode, and on the bus electrode; forming an emission layer on the first intermediate layer corresponding to the pixel electrode; forming a first opening by removing a portion of the first intermediate layer on the bus electrode to expose at least a part of the bus electrode; and forming an opposite electrode corresponding to the pixel electrode and the bus electrode to contact the bus electrode through the first opening of the first intermediate layer.
