Abstract: An electroluminescent element wherein an electrode 1, an electroluminescent layer 2, a high-refractive-index layer 3 (a transparent electrode layer 3A and an intermediate layer 3B) and a translucent body 4 are sequentially laminated. On light-emitting-surface side of the high-refractive-index layer 3 and the translucent body 4, layers 5A and 5B individually having a light-scattering function are provided respectively. The presence of the light-scattering layers 5A and 5B on the light-emitting-surface side of the high-refractive-index layer 3 and the translucent body 4 enables to emit light from the electroluminescent element through multiple scattering of guided light, which travels inside the translucent body 4 in the planar direction while being totally reflected by the interface between the translucent body 4 and air, and other guided light, which travels inside a thin film including the electroluminescent layer 2 and the high-refractive-index layer 3.

Abstract: 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.
