An organic light-emitting display apparatus includes a thin film transistor (TFT) including an active layer, a gate electrode, source and drain electrodes, a first insulating layer between the active layer and the gate electrode, and a second insulating layer between the gate electrode and the source and drain electrodes, a capacitor including a first electrode on a same layer as the active layer and a second electrode on a same layer as the gate electrode, a first contact layer of a same material as the second electrode, a second contact layer on the first contact layer, the second contact layer being of a same material as the gate electrode, a pixel electrode that contacts an edge of the first contact layer and is on an opening in the second insulating layer, an organic emission layer on the pixel electrode, and a counter electrode on the organic emission layer.
