Abstract:
1. A method of manufacturing an organic light-emitting diode (OLED) display apparatus, the method comprising: forming a first gate electrode on a substrate; forming a gate-insulating layer on the first gate electrode; forming the active layer on the gate-insulating layer; forming an interlayer insulating layer on the active layer; forming source and drain electrodes on the interlayer insulating layer; forming a planarization layer on the source and drain electrodes; forming a pixel electrode on the planarization layer; forming a pixel-defining layer (PDL) on the pixel electrode and the planarization layer; forming a first opening for exposing a portion of the planarization layer corresponding to the first gate electrode by etching the PDL and the planarization layer, and a second opening for exposing a portion of the pixel electrode, by etching the PDL; and forming an opposite electrode facing the pixel electrode in the first opening and facing the first gate electrode in the second opening.
