摘要:
A phosphor (5) comprises fluorescent particles (11), a coating film (12) for coating the particles (11), and an insulation film (13) for further coating the coating film (12). The fluorescent particles (11) are formed by pulverizing a composite consisting of a fluorescent compound such as zinc sulfide (ZnS) and an auxiliary component such as Manganese (Mn) added thereto. The coating film (12) consists of e.g. Copper (Cu) and has a thickness of e.g. 2-20 nm to enhance the conductivity of electrons in the particles (11). The insulation film (13) consists of e.g. a high-permittivity organic polymer and has a thickness of e.g. 100 nm to increase the permittivity of the phosphor (5) surface.

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.
