Abstract:
A display apparatus includes a light-emitting device with improved reliability while maintaining liquid-repellent properties of peripheral layers after plasma irradiation. The display apparatus includes: a substrate; a pixel electrode disposed on the substrate; a pixel defining layer disposed on the pixel electrode and having an opening that exposes a central portion of the pixel electrode; and a liquid-repellent layer disposed on the pixel defining layer and having an upper surface having a concavo-convex structure.
