Abstract:
A multi-colored organic electroluminescence device comprising:a transparent substrate; a plurality of different phosphor layers arrayed on a surface of the substrate to be spaced apart from each other; a protective layer coated flatly on the phosphor layers and being formed of a polynorbornene resin as a coating resin having a curing temperature at which quenching of fluorescence for the phosphor layers does not occur, said polynorbornene resin having a number average molecular weight from 50,000 to 500,000 and formed at a temperature between 100 and 150Â° C., said protective layer having a glass transition temperature more than 100Â° C. and surface hardness more than 2H on a pencil hardness; and an organic electroluminescence cell formed on the protective layer and including an organic light-emitting layer for emitting light when electric charges are injected therein, said phosphor layers and said light-emitting layer being arranged such that the phosphor layers absorb luminescence from the light-emitting layer to cause the phosphor layers fluorescent.
