Abstract
A method of forming a fluorescent screen where a pigment film and a fluorescent film are deposited on a surface of a light transmissive substrate, the method comprising: coating a pigment dispersion liquid on the surface of the light transmissive substrate to form a coated film; and forming a pigment film by drying the coated film; wherein drying of the coated film is performed under the conditions that a temperature of corner portions of the light transmissive substrate is controlled to not lower than 36° C., or that drying means which is exclusively assigned to dry the corner portions of the coated film is employed.

A method of forming a fluorescent screen where a pigment film and a fluorescent film are deposited on a surface of a light transmissive substrate, said method comprising:
- coating a pigment dispersion liquid on the surface of the light transmissive substrate to form a coated film;
- and
- forming a pigment film by drying the coated film;
- wherein drying of the coated film is performed under conditions that a temperature of corner portions of said light transmissive substrate is controlled to not lower than 36° C., and at the same time, difference in temperature between a temperature of a central region and the temperature of the corner portions of said light transmissive substrate is confined to within 7° C.
A method of forming a fluorescent screen where a pigment film and a fluorescent film are deposited on a surface of a light transmissive substrate, said method comprising:
- coating a pigment dispersion liquid on a surface of the light transmissive substrate to form a coated film;
- and
- forming a pigment film by drying the coated film;
- wherein drying of the coated film is performed such that corner portions of the coated film is allowed to dry by a drying means which is exclusively assigned to dry the corner portions of the coated film in addition to separate drying means which is assigned to dry entire surface of the coated film, and at the same time, a film thickness of said pigment film is controlled to 0.3 μm or more.
