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.
