Claim:
1. An organic electroluminescent display device comprising: a substrate on which a plurality of pixels are disposed in a matrix; an under layer comprising an organic insulating film formed on the substrate, and lower electrodes each formed for each of the pixels on the organic insulating film; a pixel separation film that covers an outer edge of the lower electrode, is provided on the under layer so as to project therefrom, and defines the pixels; and an organic layer that covers the top of the under layer and the top of the pixel separation film, and includes at least a light-emitting layer, wherein a first adhesive film formed of one or more kinds of substances selected from the group consisting of amorphous carbon, diamond-like carbon, silicon, gallium, germanium, graphite oxide, and silicon carbide is formed at least partially between the top of the under layer and the pixel separation film or between the pixel separation film and the organic layer, wherein the first adhesive film covers an upper surface of the lower electrode, and the first adhesive film is formed between a lower surface of the pixel separation film and an upper surface of the organic insulating film.
