Organic polysilane composition, colored material, method of manufacturing colored material and liquid crystal display

A method of manufacturing a colored material which comprises the steps of:

• forming a film of an organic silicon compound comprised of organic polysilane containing 5% or more of any one of repeating units represented by the following general formulas (1) to (3);
• ##STR16## wherein R.sup.1 is a substituted or non-substituted hydrocarbon group;
• R.sup.2 is a substituted or non-substituted hydrocarbon group or acyl group;
• and R.sup.3 is a substituted or non-substituted silyl group or polysilane skeleton;
• irradiating a prescribed portion of the organic silicon compound film with ultraviolet rays;
• coloring the irradiated portion of the organic silicon compound film by immersing the organic silicon compound film in a solution containing a color component;
• and
• heat-drying the organic silicon compound film, thereby converting the colored portion of the organic silicon compound film into a three-dimensional structure.

A liquid crystal display which comprises:

• a pair of transparent substrates facing each other;
• a pair of transparent electrodes, each disposed on a main surface of each of the transparent substrates so as to face each other;
• a liquid crystal between the pair of transparent substrates with each of the electrodes interposed therebetween;
• and a color filter interposed between one of the transparent substrate and the transparent electrode formed on the main surface of said one of the transparent substrate;
• wherein said color filter is formed of a colored material provided with a colored layer comprising a silicon-based matrix comprised of a photo-oxidized organic polysilane and containing a coloring component, said silicon-based matrix containing 5 atomic % or more of silicon atoms bonded through only one of its bonds to an organic residual group, based on the total number of silicon atoms in the silicon-based matrix.
