METHOD OF FORMING FLUORESCENT SURFACE AND IMAGE DISPLAY UNIT

摘要

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 DEG 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 DEG C and pressures of 10-10000 N/cm<2>. This method enhances the film forming property of a metal back layer and prevents cracks and pinholes in the metal back layer. <IMAGE>
