ABSTRACT:
A method for forming a phosphor screen comprising the step of forming a phosphor layer containing a thermoplastic resin on the inner surface of a face plate, the step of pressurizing the phosphor layer being heated to plasticate the thermoplastic resin and smooth the surface of the phosphor layer, and the step of forming a metal film on the surface-smoothed phosphor layer and heating the face plate. Thermoplastic resin having a softening temperature of 50–350° C. can be used in the phosphor layer, and 0.05–50 wt % of such a thermoplastic resin in solid content ratio is contained in the layer. Heating/pressurizing conditions preferably involve temperatures of 50–350° C. and pressures of 10–10000 N/cm2. This method enhances the film forming property of a metal back layer and prevents cracks and pinholes in the metal back layer.
