Abstract:
An organic electroluminescent display device includes: a substrate; plural anodes that are formed in respective pixels; pixel separation films that cover at least an edge of the respective anodes between the respective pixels; an organic layer that covers a display area over the plurality of anodes, and the pixel separation films, and includes at least a light emitting layer; a cathode that is formed on the organic layer; and a counter substrate that is arranged on the cathode so as to face the substrate, in which the anodes each include: a contact area that comes in contact with the organic layer, and faces a corresponding pixel of the counter substrate, and a peripheral area that is formed around the contact area, and faces pixels around the corresponding pixels of the counter substrate. The organic electroluminescent display device can realize higher definition, higher luminance, and prevention of color mixture.
