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.

Abstract: A mask assembly includes a first mask having a first opening and at least one second mask disposed on the first mask, each at least one second mask including a deposition area having second openings, an inner area surrounding the deposition area, and an outer area having third openings which surround the margin area. A line defining the outer boundary of an inner surface which defines the first opening overlaps the inner area when viewed in plan.
