摘要:
The electroluminescent device successively comprises a cathode, an electroluminescent layer, a transparent electrode layer, an evanescent light-scattering layer comprising a matrix composed of a low-refractive material containing light-scattering particles, and a transparent sheet/plate. Such an electroluminescent device is decreased in total reflection not only at a boundary surface between a transparent substrate and an outside air layer but also at a boundary surface of the transparent electrode layer on its light extraction side, and therefore, is considerably improved in light extraction efficiency. In addition, in the electroluminescent device provided with a barrier layer, the transparent electrode layer and the electroluminescent layer can be well protected so that deterioration of electroluminescent pigments and occurrence of dark spots can be effectively prevented, resulting in enhanced-life of the device.
