Abstract: An organic light-emitting diode (OLED) display and a method of manufacturing the same are disclosed. In one aspect, the OLED display includes a substrate, a plurality of pixel electrodes formed on the substrate and separated from each other. The OLED display also includes an opposite electrode formed as one body and corresponding to the pixel electrodes, wherein the thickness of the opposite electrode varies depending on a position. The OLED display further includes an intermediate layer formed between the pixel electrodes and the opposite electrode, wherein the intermediate layer includes at least an emission layer.
