Abstract
A method of manufacturing an organic light-emitting display apparatus includes: forming a pixel electrode on a substrate; forming a pixel-defining layer (PDL) having an opening exposing at least a part of the pixel electrode; forming an intermediate layer including 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; forming a protective layer including 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 and contacts the PDL; and forming an opposite electrode on the PDL, the opposite electrode having an opening exposing at least a part of the protective layer and electrically connected to the protective layer.
