An organic light-emitting display apparatus includes a substrate, a pixel electrode disposed on the substrate, a pixel-defining layer (PDL) disposed on the pixel electrode and having an opening exposing at least a part of the pixel electrode, an intermediate layer, a protective layer, and an opposite electrode be disposed on the PDL and having an opening exposing at least a part of the protective layer, wherein the opposite electrode is electrically connected to the protective layer. The intermediate layer may include a central portion disposed on the pixel electrode, an edge portion that extends from the central portion and contacts the PDL, at least one common layer, and an organic emission layer. The protective layer may include a central portion disposed on the central portion of the intermediate layer and an edge portion that extends from the central portion of the protective layer.
