<P>PROBLEM TO BE SOLVED: To provide a transparent cathode having high light transmittance, excellent in conductivity and easy to manufacture, and an anode structure in which a Fermi level matches with the level of an organic EL hole transport material, in an organic electoluminescent element. <P>SOLUTION: This organic electroluminescent element has a substrate, a first electrode structure installed on the substrate and provided with at least one metal layer and an opaque metal oxide layer, an organic layer installed on the electrode structure, and a second electrode structure installed on the organic layer. The first electrode is an anode, and the opaque metal oxide layer is a silver oxide. The second electrode structure has a transparent dielectric layer of a high refraction index as a main component, and all materials used can be deposited by a thermal vapor deposition method. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
