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 deposition mask assembly including: a frame, a pair of auxiliary masks and a deposition divided mask. The frame includes an opening area through which deposition material passes, and first, second, third and fourth side portions which collectively define the opening area. The pair of auxiliary masks are on the frame, fixed to the first and third side portions which face each other in a first direction with respect to the opening area thereof, and disposed respectively adjacent to the second and fourth side portions which face each other in a second direction crossing the first direction. The divided mask is spaced apart from each of the pair of auxiliary masks and fixed to the first and third side portions. In the second direction, a width of the pair of auxiliary masks is less than a width of the divided mask.
