22 ABSTRACT OF THE DISCLOSURE A method for manufacturing a phosphor screen used in a color CRT takes the steps of multilayering a red phosphor layer, a green phosphor layer, a blue phosphor layer, and a non-luminescent layer being laid between the adjacent color phosphor layer, cutting the multilayered block into filmy pieces toward the thickness, adhering or pressurizing the filmy cut pieces on a glass plate for front panel of the color CRT, and burning the cut pieces. This method makes it possible to efficiently manufacture a high-definition and high- resolution color phosphor screen and form fine RGB stripes. This method, thus, may apply to a small-sized CRT about which the realization of the high-definition and high-resolution color phosphor screen has been difficult.
