Abstract

PURPOSE: To avoid the coloring of front glass into brown due to electron beam emitting black substance film group, by forming the black substance film group of the light emitting material layer with using carbon and a substance blocking the transmission of electrons.
CONSTITUTION: The light emitting material layer 2 is constituted by the fluorescent substance film groups 13 to 15 formed on the front glass plate of a color Braun tube, black substance film group 12 formed to fill up the clearance of the fluorescent substance film group, and aluminum thin film 16 attached on the black film group and fluorescent substance film group. Further, the black film group 12 is formed by using the substance blocking the transmission of electrons, for example, nickel oxide, and with carbon.
