Abstract: A display device includes a substrate having a light emitting area and a non-light emitting area; a first anode electrode on the light emitting area of the substrate; a pixel defining layer on the non-light emitting area of the substrate and defining a first opening; an organic separator layer on the pixel defining layer and defining a second opening; a first light emitting layer on the first anode electrode; a common electron layer on the first light emitting layer and the organic separator layer; and a common electrode on the common electron layer, wherein the organic separator layer does not overlap the light emitting area, and overlaps the non-light emitting area to be in contact with the pixel defining layer, the first light emitting layer, and the common electron layer.
