Abstract
An embodiment of a display device includes a substrate including a display area; an organic layer and having a protrusion protruding in a thickness direction of the substrate and overlapping the display area; a first electrode on the organic layer and overlapping the display area; a pixel defining layer covering the protrusion and an edge of the first electrode and having an opening portion overlapping the first electrode; an emission layer on the first electrode and overlapping the opening portion; and a second electrode on the emission layer, wherein the pixel defining layer includes an inorganic material, and a first distance from an upper surface of the substrate to a lower surface of the first electrode is less than a second distance from the upper surface of the substrate to an upper surface of the protrusion, the lower surface of the first electrode facing the upper surface of the substrate.
