ABSTRACT:
A method of electrophotographically manufacturing a viewing screen including a filter layer of pigment particles for a cathode-ray tube (CRT), which comprises the steps of first-coating of volatilizable conductive layer, second-coating the conductive layer with a volatilizable photoconductive layer, first-establishing a uniform electrostatic charge over the whole surface of the photoconductive layer, first-exposing selected areas of the photoconductive layer to a light source, first-developing the discharged, exposed areas with one kind of charged pigment particles, and fixing the developed pigment particles to the photoconductive layer to form a filter layer beneath one of first to third color-emitting phosphor particles. Then, the one of first to third color-emitting phosphor particles is formed on the filter layer by a electrophotographically manufacturing method.
