Color filter, method for manufacture thereof and liquid crystal

Method of producing color filter using a micellar disruption method

A process for producing a thin film comprising electrotreating a dispersion or solution obtained by dispersing or dissolving a hydrophobic substance powder in an aqueous medium with a surfactant having a HLB value of 10.0 to 20.0, under conditions for forming a thin film of the hydrophobic substance on a cathode. The thin film of a hydrophobic substance can be formed on base metals such as aluminum, which can be applied to photosensitive materials and the like.

Process for producing thin films

A process for producing color filters, which comprises dispersing or dissolving pigments and the like having spectral properties in three primary colors, and a structure reinforcing resin in an aqueous medium, in the presence of a surfactant comprising a ferrocene compound, to prepare micelle solutions of dispersions in each color, and dipping the patterned electroconductive transparent substrate to be subjected to electrolytic treatment in each color, and thus forming a color-separated filter on the substrate. The color filter produced according to the above process can be utilized for display elements of filters, such as liquid crystal display devices, electrochromic display devices, latitude display devices, plasma display panels, spectroscopic devices, solid-state photographic devices and dimmers.

Process for producing color filter

Disclosed is a process for producing thin films, which comprises dispersing or dissolving inorganic substance or hydrophobic organic substance in an aqueous medium in the presence of a surfactant having HLB value of 10 to 20, to obtain micelle solution or dispersion, dipping a semiconductive or photoconductive substrate into said micelle solution or dispersion, applying an electric potential on said substrate if necessary, and irradiating lights on the contact interface of said mecelle solution or dispersion and said substrate, and thus forming thin films of said inorganic substance or hydrophobic inorganic substance on said substrate. Also disclosed is a process for producing color filters having excellent properties, which comprises forming color separation filter on the substrate according to the above-mentioned process, by the use of pigments or dyes in three primary colors of red, green, and blue.

Process for producing thin films and color filters

A process for producing an organic thin film, wherein a hydrophobic organic substance is admixed with a ferrocene compound in an aqueous medium to solubilize the hydrophobic organic substance and form a micelle solution. The micelle solution is electrolyzed to form thin film of the hydrophobic organic substance on an anode. The ferrocene compound has the formula: ##STR1## wherein R.sup.1 and R.sup.2 are identical or different and are a hydrogen, a methyl group, a methoxyl group, an amino group, a dimethylamino group, a hydroxyl group or halogen, X is ##STR2## M is an alkali metal or an alkaline earth metal, a is an integer of 1 to 4, b is an integer of 1 to 5, k is an integer of 1 to 18 and m is an integer of 0 to 4.
