Abstract

PURPOSE:To prevent emission characteristic from deteriorating, to obtain excellent life characteristic, and to prevent chromatic misalignment by forming a film on a shadow mask by using powder made by mixing powder of Bi2O3 with powder of oxide of specific metals. CONSTITUTION:Using powder made by mixing powder of Bi2O3 with powder of a metal other than Bi or powder of oxide of a metal other than Bi, a film is formed on a shadow mask. The powder of the metal other than Bi is that of Si, Ge, Ti, Zr, Al, Zn, Pb, Pe, Mn, Sb, W or rare earth element. The powder of oxide of the metal other than Bi is that of SiO2, GeO2, TiO2, ZrO2, Al2O3, ZnO, PbO, Ga2O3, Fe2O3, Mn2O3, Sb2O3, WO3 or oxide of rare earth element. Further, the mean particle diameter of each powder is made to be 0.05-2mum.
