Abstract
A transparent inorganic intermediate layer extends between a color filter layer and a phosphor layer in a color display device. The intermediate layer stops electrons before they can penetrate the color filter layer. Aging phenomena which adversely affect the effectiveness of the color filter layer are thus precluded. It is alternatively possible to use hitherto useless pigments, in particular pigments which are unstable when they are exposed to an electron bombardment in the color filter layer (or layers). By virtue thereof, the effectiveness of the color filter layer has been increased.
