Abstract
In a method for manufacturing a phosphor screen of a cathode ray tube, a first photo-resist layer is coated on an inner surface of a panel of the cathode ray tube except at predetermined locations. A second photo-resist layer dispersed with pigment particles is coated on the first photo-resist layer and at the predetermined locations. The second photo-resist layer is exposed at the predetermined locations from an opposite side of the panel. The first photo-resist layer is dissolved and the second photo-resist layer is removed from the first photo-resist layer so as to form a color filter layer at the predetermined locations. A phosphor layer is formed on the color filter layer.
