Abstract: A display apparatus includes a substrate, a pixel circuit layer having at least one thin-film transistor on the substrate, a first layer disposed on the pixel circuit layer and having a first opening, and a display element disposed in the first opening and including a first electrode, an emission layer, and a second electrode, which are sequentially stacked. The first electrode extends from an inner surface of the first layer defining the first opening along an upper surface of the first layer, and the emission layer extends on the first electrode along the inner surface of the first layer.
