Abstract
A method of manufacturing a phosphor screen of a cathode ray tube, comprises forming a pattern having a particle-receptive adhesive surface on an inner surface of a faceplate having a peripheral wall, rotating the faceplate about an axis perpendicular to its inner surface and passing its center, and charging phosphor particles onto the inner surface of the faceplate during or before rotation thereof so as to allow the phosphor particles to slide on the inner surface of the faceplate and to attach to the particle-receptive adhesive surface. The method can form a phosphor film having a uniform and sufficient thickness without an irregularity in the amount of phosphor attached.

A method of manufacturing a phosphor screen of a cathode ray tube, comprising:
- forming a pattern having a particle-receptive adhesive surface on an inner surface of a face plate having a peripheral wall;
- rotating said face plate at a rotational frequency of 1 to 100 rpm about an axis perpendicular to an inner surface thereof and passing a center thereof, the axis of the face plate being inclined with respect to a vertical axis;
- and
- charging phosphor particles onto the inner surface of said face plate during or before rotation thereof so as to allow the phosphor particles to slide on the inner surface of said face plate and to attach to said particle-receptive adhesive surface.
