Abstract
A method of forming a phosphor screen in which a color filter layer is formed between a phosphor layer and an inner surface of a panel having a slurry in which a fine particle pigment and transparent particles are dispersed into a photosensitive liquid coated on the inner surface of the panel. Then, the color filter layer is formed by exposure and development. When the color filter layer that constitutes one portion of a phosphor screen of a color cathode ray tube is formed in this manner, an adhesive force with which the color filter layer is bonded onto the panel can be increased and a transmittance of the color filter layer can be improved.
