Patent ID: 7722965

Claim:
An organic electroluminescence device comprising: an organic layer comprising an emissive layer; a pair of electrodes comprising an anode and a cathode, and sandwiching the organic layer, wherein at least one of the electrodes is transparent; a transparent layer provided adjacent to a light extracting surface of the transparent electrode; and a region substantially disturbing reflection and refraction angle of light provided adjacent to a light extracting surface of the transparent layer or in an interior of the transparent layer, wherein the transparent layer has a refractive index substantially equal to or more than the refractive index of the emissive layer, wherein the transparent layer comprises a polycarbodiimide resin represented by the following general formula (I): R 1 —N═C═N(—R—N═C═N-)n-R 1 (I) wherein R, R 1 and n represent organic diisocyanate residue, organic monoisocyanate residue and an integer of 1 to 100, respectively.
