Abstract
A method of manufacturing a phosphor screen of uniform thickness on an inner surface of a panel of a cathode ray tube, comprising the steps of forming a powder-receptive adhesive pattern on the inner surface of a substantially rectangular panel having a skirt portion at the periphery, forming a sealed vessel consisting essentially of a container for containing phosphor powder and the panel by combining integrally the container and the panel so that the openings of both are opposed, and rotating the sealed container about an axis parallel to the inner surface of the panel.
