Claim Text:
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 on a substrate, the pixel electrode and the bus electrode being spaced apart and electrically insulated from each other; forming a pixel-defining layer on the same layer and on the pixel electrode and the bus electrode such that at least a portion of the pixel electrode including a center of the pixel electrode and at least a portion of the bus electrode are exposed; forming an intermediate layer on an upper surface of the pixel-defining layer disposed between the pixel electrode and the bus electrode, and on the pixel electrode and the bus electrode; orienting the substrate such that the intermediate layer is located underneath the substrate with respect to a direction of gravity; forming an opening in the intermediate layer by irradiating the intermediate layer with a laser beam from underneath the intermediate layer to remove the intermediate layer on the bus electrode such that at least a portion of the bus electrode is exposed; and forming an opposite electrode corresponding to the pixel electrode and the bus electrode such that the opposite electrode contacts the bus electrode via the opening in the intermediate layer.
