ABSTRACT:
The present invention relates to an organic electroluminescent display device in which luminance and emission efficiency may be improved by forming light emitting elements of the organic electroluminescent display device in a projecting structure and provides an organic electroluminescent display device comprising a projecting structure layer formed on an insulating substrate; first electrode formed in a projecting structure on the substrate including the projecting structure layer; an organic layer formed on the first electrode; and second electrode formed on the insulating substrate, wherein the second electrode may be formed in a projected shape by the projecting structure layer so that the second electrode surrounds the organic layer.
