Abstract
The invention relates to a display device and a method of manufacturing the same. The display device includes: a substrate having a light emitting area and a non-light emitting area; a first anode electrode on the light emitting region of the substrate; a pixel defining layer on the non-emission area of the substrate and defining a first opening; an organic separation 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 separation layer; and a common electrode on the common electron layer, in which the organic separation layer does not overlap with the light emitting region in a plan view, and the organic separation layer overlaps with the non-light emitting region in a plan view to contact the pixel defining layer, the first light emitting layer, and the common electron layer.
