ABSTRACT:
Respective phosphor layers (3R), (3G) and (3B) and a light absorption layer (2) are formed on the inner surface of a panel. An intermediate layer (11) is selectively formed on the surfaces of the respective phosphor layers by using a water soluble liquid having photosensitivity and containing water dispersion vinyl polymer emulsion and partial saponification polyvinyl acetate-system photosensitizer and then a metal-backing layer (12) is formed. A color purity of a phosphor screen can be increased and a brightness thereof can be improved.
