Abstract:
A display device including a substrate that includes a circuit layer; an insulating layer on the substrate; a pixel defining layer on the insulating layer, the pixel defining layer having an opening exposing a region of a top surface of the insulating layer; a light blocking layer covering a top surface and a side surface of the pixel defining layer; and an organic electroluminescent element in the opening, wherein the organic electroluminescent element includes a first electrode on the region of the top surface of the insulating layer exposed through the opening; at least one organic layer on the first electrode; and a second electrode on the at least one organic layer.
