An organic light-emitting diode (OLED) display and a method of manufacturing the same are disclosed. In one aspect, the OLED display includes a plurality of pixels, each of the pixels including at least one wiring configured to receive an electrical signal and a storage capacitor formed on the same layer as the wiring. The wiring includes a first conductive pattern layer, an intermediate insulation pattern layer, and a second conductive pattern layer that are sequentially stacked. The first and second conductive pattern layers are electrically connected to each other through a first via hole.
