    • On a back electrode 1, a sealing polymer layer 3 of low water-permeability serving as an insulating layer, a plurality of dielectric cells 9 containing fluorescent particles 7 embedded in a binding material 5 of low-leakage-current high dielectric constant, a binding material layer 11, and a transparent conductive layer 13 made of ITO are built up in a multilayer structure and a transparent protecting film 15 made of a PET film is lastly formed on the transparent conductive layer 13. A luminous layer is composed of the dielectric cells 9. The fluorescent particles 7 contained in the luminous layer are made of Zinc, Sulfur, Manganese, Copper, Silicon, and Titanium. The mass ratio of Zinc is 1, that of Sulfur 3.1, that of Manganese 0.3, that of Copper 0.7, that of Silicon 3.5, and that of Titanium 5.6, and the sum of these numeric values is 14.2.
    • 在背面电极1上,作为绝缘层的低透水性的密封聚合物层3,包含嵌入在低泄漏电流高介电常数的粘结材料5中的荧光粒子7的多个电介质电池9, 材料层11和由ITO制成的透明导电层13构成多层结构,最后在透明导电层13上形成由PET膜制成的透明保护膜15.发光层由介质电池 包含在发光层中的荧光颗粒7由锌,硫,锰,铜,硅和钛制成。 锌的质量比为1,硫3.1,锰0.3,铜3.5,钛5.6的数量和这些数值之和为14.2。
