摘要： 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 (1) is tilted with respect to a vertical axis (2) and is rotated having a tilt axis (3) as a central axis to spread a phosphor slurry (9) over almost the entire area of an inner face of the glass panel (1). In the shake-off process, by rotating the glass panel (1), excess phosphor slurry is shaken off and the excess phosphor slurry is recovered in phosphor-slurry recovery members (4) provided at the four corners of the glass panel (1). In the drying process, the phosphor slurry is dried. In this method, the tilt angle and rotation speed of the glass panel (1) 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 (1) can be obtained.
