    摘要： A dispersion solution of colloidal silica is coated on a pigment layer of a substrate composing a filter layer and then dried. Accordingly, the state of the front surface of the filter layer (pigment layer) is controlled without affecting the filter layer (pigment layer). A phosphor layer is formed on the filter layer (pigment layer).
    The method has application to phosphor screens in cathode ray tubes and plasma display panels for improving their uniformity of brightness and contrast.

    摘要： In a colour picture tube (1,2,3) having a phosphor screen (5) composed of a blue-emitting phosphor, a green-emitting phosphor, and a red-emitting phosphor, the ratio A/B of the brightness A of the red-emitting phosphor to the brightness B of the blue-emitting phosphor is 1.40 or more. Thus, red colour purity is improved without a decrease of the brightness of the phosphor screen. Consequently, a colour picture tube with a wide color reproducible region can be provided.
