An organic light-emitting display apparatus that includes a thin film transistor comprising an active layer, a gate electrode, and source and drain electrodes electrically connected to the active layer; a pixel electrode formed on the same layer as the gate electrode; a light-emitting layer formed on the pixel electrode; a passivation layer formed on upper surfaces of the source and drain electrodes and upper surfaces of wirings formed on the same layer as the source and drain electrodes; an organic insulating layer that covers the thin film transistor, comprises an opening that exposes an upper surface of the pixel electrode, and directly contacts the passivation layer; and a facing electrode that is formed on the light-emitting layer, and is formed to directly contact the organic insulating layer to face the pixel electrode.
