    • An organic electroluminescence device having an anode structure on the lower surface which is effective for taking out light efficiently from the cathode on the upper surface in which the organic electroluminescence device comprises an anode, a cathode and an organic layer put between both of them. The organic layer contains an organic light emitting layer that emits light by re-combination of holes supplied from the cathode A and electrons supplied from the cathode. The cathode comprises a laminate structure of an electron injecting metal layer, and a transparent conductive layer ultra thin film which is basically light permeable. The anode contains a metal belonging to the group V or group VI of the periodical table to at least a portion in contact with the organic layer and is basically light reflective. The anode metal is selected from chromium, molybdenum, tungsten, tantalum and niobium. The anode metal has a work function of 4.8 eV or lower.
    • 一种在下表面具有阳极结构的有机电致发光器件,其有效地从有机电致发光器件包括阳极,阴极和两者之间的有机层的上表面上的阴极有效地取出光。 有机层包含通过从阴极A提供的空穴和从阴极供给的电子的重新组合而发光的有机发光层。 阴极包括电子注入金属层和基本上是透光的透明导电层超薄膜的叠层结构。 阳极含有属于周期表第V族或第VI族的金属,至少部分与有机层接触,并且基本上是光反射性的。 阳极金属选自铬,钼,钨,钽和铌。 阳极金属具有4.8eV或更低的功函数。
