An organic light-emitting display apparatus includes a substrate, and a thin-film transistor and a capacitor formed over the substrate. The apparatus further includes an interlayer insulation layer, a first organic insulating layer and a second organic insulation layer sequentially stacked over the substrate and covering the thin-film transistor and a capacitor. The first organic insulation layer includes a first hole that does not overlap with the thin-film transistor and the capacitor when viewed in a direction perpendicular to a major surface of the substrate. The apparatus further includes a pixel electrode formed over the interlayer insulating layer and the first organic insulating layer. The pixel electrode includes a first portion disposed inside the first hole and a second portion disposed over the first organic insulating layer and outside the first hole. The apparatus includes a light emission layer and an opposite layer formed over the pixel electrode.
