Abstract
A coating solution composition for forming a glass gel thin film, contains at least one material selected from the group consisting of a metal alkoxide and a polycondensate of the metal alkoxide, a coloring material, an alcohol solvent, and a dispersant having an adsorption material for the coloring material, soluble in the alcohol solvent, and having miscibility with the metal alkoxide, wherein the coloring material has an average particle size of 3 nm to 300 nm. A glass gel thin film obtained by sintering this composition at a temperature of 100.degree. to 300.degree. C. is excellent in water resistance, durability and has a high strength.
Claims10
A display device comprising a display unit and a glass gel filter having light-absorbing selectivity, which is formed on an outer surface of said display unit and prepared by sintering, at a temperature of 100.degree. to 300.degree. C., a coating film obtained by applying a coating solution to the outer surface, the coating solution containing:
- at least one material selected from the group consisting of a metal alkoxide and a polycondensate of the metal alkoxide;
- a coloring material having a granular form with an average particle size of 3 nm to 300 nm and which is substantially insoluble in the coating solution;
- an alcohol solvent;
- and
- a dispersant having an adsorption property for the coloring material, dissolved in the alcohol solvent, and immisced with the metal alkoxide;
- and
- wherein the coloring material is also in granular form in the thin film.
