Abstract
In a color liquid crystal substrate, in which a plurality of color filter elements are formed on a transparent substrate, a primary coating of an organic silicon compound containing oxide particles is formed on the color elements, and a secondary coating of a silicon dioxide is formed on said primary coating. Further, the oxide particles contained in the primary coating are concentrated and fill-in the recess portions defined among the neighboring color filter elements.
Claims20
A substrate for use of a color liquid crystal display, having a transparent substrate on which a plurality of color filter elements are formed, comprising:
- a primary coating formed on said color elements formed of an organo silicon compound containing oxide particles;
- and
- a secondary coating formed on said primary coating formed of a silicon dioxide;
- wherein said oxide particles contained in said primary coating are concentrated in recess portions which are defined among the neighboring color filter elements.
A manufacturing method of a substrate for use of a color liquid crystal display, comprising:
- forming a primary coating containing oxide particles, by depositing and curing a solution including organic silane or a hydrolysate thereof, which is expressed by the following equation, and including oxide particles;
- and
- forming a secondary coating of silicon dioxide on the primary coating by contacting the primary coating with a hydrofluosilicic acid solution which is supersaturated with silicon dioxide;
- R.sup.1.sub.n Si(R.sup.2).sub.4-n
- wherein R.sup.1 is a hydrocarbon group of 1 to 6 carbon number, a vinyl group, a methacryloxy group, an epoxy group, an amino group, a mercapto group, or an organic group including fluorine or chlorine,
