    摘要: 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.
