Zusammenfassung:To provide an organic electroluminescent element using an electrode excellent in conductivity and flexibility and excellent also in transparency as compared with ITO.SOLUTION: In an organic electroluminescent element having structure in which a plurality of layers including an anode, a cathode and an organic compound layer are laminated, the organic electroluminescent element is constituted so that an end of cathode side lamination structure is formed on a substrate and has a layer 2 of a metallic compound of which surface energy is 60 dyne/cm and more, a layer 3 of a metal simple substance, a layer 4 of a metallic oxide, and an organic compound layer 5 in the order from the end of the cathode side lamination structure.SELECTED DRAWING: Figure 1 【課題】ITOに比べて導電性やフレキシビリティに優れ、更に透明性にも優れた電極を用いた有機電界発光素子を提供する。【解決手段】陽極と陰極と有機化合物層とを含む複数の層が積層された構造を有する有機電界発光素子であって、該有機電界発光素子は、陰極側の積層構造の末端が基板上に形成され、陰極側の積層構造の末端から、表面エネルギーが60dyne/cm以上の金属化合物の層2、金属単体の層3、金属酸化物の層4、有機化合物層5をこの順に有する有機電界発光素子。【選択図】図1
