Abstract: A display apparatus includes a first pixel and a second pixel arranged on a substrate and adjacent to each other; and each including a common layer and an opposite electrode each being provided as a body; a pixel-defining layer including openings respectively corresponding to the first pixel and the second pixel and defining emission areas; and a structural layer arranged on the pixel-defining layer and including an upper surface, a first lateral surface, and a second lateral surface. The first lateral surface is connected to the upper surface and has a slope tapered in a reverse direction. The second lateral surface is connected to the upper surface and has a slope tapered in a forward direction. Each of the common layer and the opposite electrode includes a discontinuous portion disconnected by the first lateral surface.
