Abstract: An electron scattering prevention film in disclosed comprising at least the following three layers: an electrode layer deposited on a phosphor layer; a first electron scattering prevention layer deposited on the electrode layer composed of a first electron scattering prevention material having a smaller atomic number than that of the material constituting the electrode layer; and a second electron scattering prevention layer deposited on the first electron scattering prevention layer composed of a second electron scattering prevention material having a smaller atomic number than that of the material constituting the electrode layer. A bimetal action which occurs between the electrode layer and the first electron scattering prevention layer is cancelled by a bimetal action which occurs between the first electron scattering prevention layer and the second electron scattering prevention layer whereby the electron scattering prevention film is prevented from being distorted to an extent that the electrode layer peels off from the phosphor layer under variation of temperature.

Abstract: A thin-film phosphor layer can be formed by an improved deposition method involving: (1) forming a phosphor powder layer that is substantially uniformly-deposited on a substrate surface; and (2) forming a polymer binder layer to fill gaps among loosely packed phosphor particles, thereby forming a substantially continuous layer of thin film.
