Claim:
1. A method of manufacturing an organic light-emitting diode (OLED) display, the method comprising: performing a first mask process of forming an active layer of a thin-film transistor (TFT) over a substrate; performing a second mask process of i) forming a gate insulating layer over the active layer and ii) forming a gate electrode of the TFT and a first electrode of a capacitor over the gate insulating layer; performing a third mask process of i) forming an interlayer insulating layer over the gate electrode and ii) forming a contact hole in the interlayer insulating layer so as to expose a portion of the active layer; performing a fourth mask process of forming a pixel electrode over the interlayer insulating layer; performing a fifth mask process of forming source and drain electrodes a pad electrode and a second electrode of the capacitor via dry etching, wherein any one of the source and drain electrodes directly contacts a top surface of the pixel electrode, and wherein the pad electrode, the second electrode and the source and drain electrodes are formed concurrently; and performing a sixth mask process of forming a pixel-defining layer at least partially covering ends of the pixel electrode.
