Abstract: A display device includes a via layer disposed on a substrate and including a via groove having a shape recessed from a first surface to a second surface of the via layer. A first electrode is disposed on the first surface. A pixel-defining film is disposed on the via layer and the first electrode. A first pixel-defining film through-hole passes through the pixel-defining film in a thickness direction and exposes the first electrode. A second pixel-defining film through-hole passes through the pixel-defining film in the thickness direction. The second pixel-defining film through-hole is spaced apart from the first pixel-defining film through-hole and overlaps the via groove. An emission layer is disposed on an exposed portion of the first electrode. A protrusion is disposed on the pixel-defining film and includes a protrusion through-hole which passes through the protrusion in the thickness direction and overlaps the second pixel-defining film through-hole.

Abstract: A deposition mask includes: a plurality of sub-masks through which deposition material passes to a base layer to form a deposition layer defining a hole therein, each of the sub-masks including: an aperture through which the deposition material passes to the base layer, a total planar area of the aperture corresponding to less than a total planar area of the deposition layer, and a masking surface at which the deposition material does not pass through the sub-mask, the masking surface including a hole-forming portion of which a total planar area thereof corresponds to a total planar area of the hole defined in the deposition layer. The hole-forming portions of the sub-masks have a same shape and planar area as each other, and within each sub-mask, the shape of the hole-forming portion is nested within a shape of the aperture.
