Patent ID: 7094120

Claim:
A method for manufacturing a phosphor screen substrate, comprising the steps of: applying a liquid containing a resin on a phosphor layer disposed on a substrate; drying the liquid containing a resin, which is applied on the phosphor layer, so that a resin layer is formed on the phosphor layer; heating the resin layer formed on the phosphor layer by the drying step by infrared radiation to a temperature in the range of from a glass transition temperature of a resin forming the resin layer to the melting point thereof, wherein the heating step is performed independently from the driving step; forming a metal film on the heated resin layer; and pyrolyzing the resin layer provided with the metal film thereon, wherein the resin layer forming step comprises the substeps of adhering a laminate, which is composed of a release film and the resin layer formed thereon, onto a surface of the phosphor layer so that the resin layer is brought into contact therewith, and removing the release film, and wherein the resin layer heating step is performed so that the difference in height of the surface of the resin layer, which is obtained after the resin layer heating step, on the phosphor layer is in the range of from 20% to less than 100% of a median of distribution of phosphor particles forming the phosphor layer.
