Claim:
1. An organic light-emitting display apparatus comprising: a substrate; a thin film transistor on the substrate and comprising an active layer, a gate electrode, a source electrode, and a drain electrode; a first interlayer insulating layer between the gate electrode and the source electrode and between the gate electrode and the drain electrode, the first interlayer insulating layer comprising an inorganic material; a second interlayer insulating layer between the first interlayer insulating layer and the source electrode and between the first interlayer insulating layer and the drain electrode, the second interlayer insulating layer comprising an organic material; a first organic layer on the source electrode and the drain electrode; a capacitor comprising a first electrode comprising the same material as that of the gate electrode, a second electrode comprising the same material as that of the source electrode and the drain electrode, and the first interlayer insulating layer between the first electrode and the second electrode; a pixel electrode in an aperture in the second interlayer insulating layer at an area adjacent to the thin film transistor and the capacitor, the pixel electrode being coupled to one of the source electrode and the drain electrode; an organic emission layer on the pixel electrode; an opposite electrode on the organic emission layer; and a pad electrode on the same layer as the source electrode and the drain electrode.
