摘要
PURPOSE: To form the phosphor screen having the excellent adhesive property by forming the resist film having a predetermined pattern on the inner surface of a panel, and coating the whole surface of the resist film with the red, green and blue color paste, and performing the reverse development to eliminate the resist film or the like and obtain a red, a green and a blue filters. ;CONSTITUTION: A color selecting electrode is used as an optical mask to expose the photosensitive film 6 at a green and a blue positions with the ultraviolet rays, and the development is performed with hot water to form the resist film 6A except for a position of red. Next, the whole surface of the resist film 6A is coated with the predetermined red pigment paste, which is made of red pigment and water and dispersing agent, and dried to obtain the coating film for red filter. The film 6A is decomposed by the hydrogen peroxide solution, and the reverse development is performed to form a red filter 3R. A blue filter 3B and a green filter 3G are obtained similarly. Thereafter, the filters 3R, 3B, 3G are respectively formed with a red phosphor stripe layer 3G, a blue phosphor stripe layer 4B and a green phosphor stripe layer 4G to obtain the phosphor screen made of a laminated body of these phosphor stripe layers.;COPYRIGHT: (C)1993,JPO&Japio
