Abstract
A method of manufacturing a light-emitting display apparatus and a light-emitting display apparatus are provided. The method includes forming a first photosensitive layer on a conductive material layer, forming a pixel electrode by etching the conductive material layer by using the first photosensitive layer as a mask, ashing the first photosensitive layer disposed on the pixel electrode, forming a pixel defining layer that covers an edge portion of the pixel electrode and includes a first opening overlapping the ashed first photosensitive layer, removing the ashed first photosensitive layer disposed in the first opening, forming an intermediate layer including a functional layer and an emission layer on the pixel defining layer, and forming an opposite electrode on the intermediate layer.
