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) and a first electrode of a capacitor over a substrate; performing a second mask process of i) forming a gate insulating layer and ii) forming a gate electrode of the TFT and a second electrode of the capacitor over the gate insulating layer; performing a third mask process of i) forming first and second interlayer insulating layers and ii) removing portions of the first and second interlayer insulating layers so as to form a contact hole that exposes a portion of the active layer; performing a fourth mask process of forming a pixel electrode over the second interlayer insulating layer; performing a fifth mask process of forming source and drain electrodes via dry etching, wherein one of the source and drain electrodes directly contacts a top surface of the pixel electrode; and performing a sixth mask process of forming a pixel-defining layer at least partially covering ends of the pixel electrode, wherein the first and second electrodes of the capacitor and the pixel electrode overlap each other in the depth dimension of the OLED display.
