Abstract

A display apparatus includes: a first pixel electrode and a second pixel electrode spaced apart from each other on a substrate; a pixel definition layer including an opening exposing a central portion of each of the first pixel electrode and the second pixel electrode; an intermediate layer on the first pixel electrode, the second pixel electrode, and the pixel definition layer and including a through hole exposing at least a portion of an upper surface of the pixel definition layer between the first pixel electrode and the second pixel electrode; an opposite electrode on the intermediate layer to face the first pixel electrode and the second pixel electrode; and an inorganic encapsulation layer over the opposite electrode.
