Abstract: A display device and a method of manufacturing the same are provided. The display device includes: a pixel-circuit layer including a pixel circuit on a substrate; and a light-emitting-element layer on the pixel-circuit layer, wherein the light-emitting-element layer includes: an anode electrode; a pixel defining layer covering at least a portion of the anode electrode, the pixel defining layer forming a pixel defining opening exposing at least a portion of the anode electrode; a light emitting structure electrically connected to the anode electrode; and a cathode electrode electrically connected to the light emitting structure, wherein the pixel defining layer includes a rounded upper surface having a rounded corner, the rounded upper surface including an inclined side surface facing the pixel defining opening, and wherein an angle between the inclined side surface and a top surface of the anode electrode is in a range of 15 degrees to 45 degrees.
