Abstract
A method for manufacturing a screen including forming a phosphor layer on an inner surface of a panel where a black matrix layer is present; applying and drying a filming composition comprising an acryl emulsion having a molecular weight of 1.5-2.5 million and a decomposition starting temperature of 200.degree.-250.degree. C. as a main component on the phosphor layer to form a film; and forming a meal layer on the film.
