Organic electroluminescence device |
摘要 |
An organic electroluminescence device comprises a cathode, an anode and a layer of an organic thin film comprising one or a plurality of layers and disposed between the cathode and the anode, wherein at least one of the layers in the layer of an organic thin film comprises a laminate of a layer comprising a metal complex having an energy gap of 2.8 eV or greater and a layer of a host material. The organic electroluminescence device exhibits a higher efficiency of light emission and has a longer life than conventional devices while the emitted light has a high luminance.
