A method of manufacturing an organic light-emitting diode (OLED) display includes forming a thin film transistor and a first storage capacitor electrode, forming a second storage capacitor electrode overlapping the first storage capacitor electrode with a passivation layer covering the first storage capacitor electrode, the passivation layer being interposed between the second storage capacitor electrode and the first storage capacitor electrode, sequentially forming a first anode electrode and an insulating layer to overlap the second storage capacitor electrode on an overcoat layer covering the second storage capacitor, forming a pixel contact hole exposing a drain electrode of the thin film transistor through the overcoat layer and the passivation layer, and forming a second anode electrode coming in contact with the drain electrode and the first anode electrode and overlapping the first anode electrode with the insulating layer interposed between the second anode electrode and the first anode electrode.
