Abstract
There is provided a phosphor screen forming method in which a metal-backing layer formed after baking can be prevented from becoming nonuniform. A phosphor layer (1), an intermediate solution film layer (2), and a lacquer film layer (3) are formed on an inner surface of a panel (P). The intermediate film layer solution contains 1 weight % of oxalic acid. The oxalic acid in the intermediate film layer solution is crystallized by evaporating and drying the intermediate film layer solution and the lacquer, and a crystallized material (4) is grown (FIG. 5A). Thereafter, an aluminum layer (5) is formed on the lacquer film layer (3) (FIG. 5B), and the intermediate solution film layer (2) and the lacquer film layer (3) are removed by baking (FIG. 5C).
