Title:

METHOD OF FORMING FLUORESCENT SURFACE AND IMAGE DISPLAY UNIT

Document Type and Number:

WIPO Patent Application WO/2002/093608

Kind Code:

A1

Abstract:

A method of forming a fluorescent surface comprising the step of forming on the inner surface of a face plate a fluorescent layer containing thermoplastic resin, the step of pressurizing the fluorescent layer being heated to plasticize the thermoplastic resin and smooth the surface of the fluorescent layer, and the step of forming a metal film on the surface−smoothed fluorescent layer and heat treating the face plate. Thermoplastic resin having a softening temperature of 50−350 ° C is used in the fluorescent layer, and 0.05−50wt.% of such a thermoplastic resin in solid content ratio is contained in the layer. Heating&sol pressurizing conditions preferably involve temperatures of 50−350 ° C and pressures of 10−10000 N&sol cm². This method enhances the film forming property of a metal back layer and prevents cracks and pin holes in the metal back layer.
