摘要：
A photoresist film containing a phosphate of a formalin condensate of diazodiphenylamine, 2.5-bis(4'-azide-2'-sulphobenzilidene) cyclopentanone Na, polyvinylalcohol, and polyvinylpyrrolidone is formed on the inner surface of a faceplate. The photoresist film is hardened by light exposure using a point or linear light source, which is essentially a circular light source, via a shadow mask having a large number of apertures. A light absorbing film is formed on this photoresist film. Then the hardened photoresist film and the light absorbing film on top of it are removed using a peeling agent.
