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.

Abstract: Provided are a display apparatus and a method of manufacturing the same. The display apparatus includes a substrate, a first conductive layer disposed on the substrate, and a first insulating pattern disposed on the first conductive layer. The first insulating pattern includes a fluorine compound and a nitrogen compound. The nitrogen compound is represented by Formula 1: NR1R2R3OH wherein in Formula 1, R1 to R3 are each independently selected from hydrogen, a substituted or unsubstituted C1-C20 alkyl group, a substituted or unsubstituted C6-C30 aryl group, and a substituted or unsubstituted C7-C30 aralkyl group.
