Abstract: An organic light-emitting diode (OLED) display and a method of manufacturing the same are disclosed. In one aspect, the display includes a plurality of pixel electrodes positioned over a substrate and separate from each other, a plurality of auxiliary wirings between the pixel electrodes, a pixel-defining layer over the pixel electrodes except for a central portion of the pixel electrodes and at least a portion of each of the auxiliary wirings, an intermediate layer over the pixel-defining layer and having a plurality of openings formed over the portion of each of the auxiliary wirings, and an opposite electrode positioned over the intermediate layer and facing the pixel electrodes, the opposite electrode electrically contacting the auxiliary wirings via the openings. The auxiliary wirings extend in a first direction and separate from each other by a first distance. The openings are aligned in a diagonal direction crossing the first direction.
