Abstract: A method of manufacturing an organic light-emitting display apparatus includes forming a pixel electrode, a bus electrode and a pixel defining layer on a same layer on a substrate, the pixel defining layer exposing a center of the pixel electrode and a portion of the bus electrode, forming an intermediate layer on the pixel-defining layer and on the pixel electrode and the bus electrode, orienting the substrate such that the intermediate layer is located underneath the substrate, 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, exposing at least a portion of the bus electrode, and forming an opposite electrode such that the opposite electrode contacts the bus electrode via the opening in the intermediate layer.
