A method of manufacturing a cathode-ray tube comprises a process of forming a phosphor screen. The process comprises an application process, a shake-off process, and a drying process. In the application process, a glass panel is tilted with respect to a vertical axis and is rotated having a tilt axis as a central axis to spread a phosphor slurry over almost the entire area of an inner face of the glass panel. In the shake-off process, by rotating the glass panel, excess phosphor slurry is shaken off, and the excess phosphor slurry is recovered in phosphor-slurry recovery members provided at the four corners of the glass panel. In the drying process, the phosphor slurry is dried. In this method, the tilt angle and rotation speed of the glass panel at least in one process out of the application process, the shake-off process, and the drying process is changed at least in two stages. Thus, using large phosphor particles capable of obtaining a high luminance, a cathode-ray tube in which a phosphor screen, with uniform distribution of the phosphors and without a cross phenomenon, wall stain, and liquid spill onto the inner face, is formed on an inner face of a glass panel can be obtained.

Method of manufacturing cathode-ray tube

A color image receiving tube comprising three color (red, green and blue) phosphor screens on an inner surface of a face-plate; wherein at least two of said three color phosphor screens are coated with pigments; and wherein said three color phosphor screens have a total reflective brightness less than 70% that of three color phosphor screens with no pigment coating. According to the above-mentioned constitution, a color image receiving tube having a higher emisson brightness and contrast is achieved as compared to a color image receiving tube having the same reflective brightness, where the reflective brightness is obtained by lowering the light transmittance of its face-plate.
