Abstract: A glass substrate manufacturing method and a color cathode ray tube manufacturing method manufactures a front substrate on which a phosphor layer is formed. In an application process a phosphor slurry of one color is applied onto an inner surface of a glass substrate on which a phosphor pattern in at least one color has already been formed. Then, in a spreading process, the glass substrate is rotated about an axis located at the approximate center of the inner surface to make the phosphor slurry spread out over its inner surface. Following this, in a draining process the glass substrate is tilted to a first tilt angle of more than 90° to drain excess slurry off the inner surface of the glass substrate, a tilt angle being formed between a vertical axis and an axis orthogonal to an outer surface of the glass substrate. In a spinning process the glass substrate is returned to a second tilt angle smaller than the first tilt angle, and rotated.

Abstract: 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.

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.
