<p><P>PROBLEM TO BE SOLVED: To provide a light-emitting composition which gives an inorganic system electroluminescent sheet with high productivity at low cost and efficiently and has prescribed light transmissivity (transparency) at the time of no application of a voltage, an inorganic system electroluminescent sheet which is formed by using the composition and capable of mass production, and its manufacturing method. <P>SOLUTION: In this inorganic system electroluminescent sheet, the light-emitting composition which contains the inorganic system electroluminescent body and a binder resin, and in which the content of the inorganic electroluminescent body is 0.5 pts.wt. or larger and smaller than 100 pts.wt. with respect to the binder resin 100 pts.wt., at least a first transparent base material, a first transparent electrode, an inorganic electroluminescent layer, a first transparent electrode, and a second transparent base material are laminated in this order. The inorganic electroluminescent layer is formed of the light-emitting composition, and light transmittance in a wavelength 550 nm at the time of no light-emission is 60% or higher. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
