Abstract: PURPOSE:To obtain a color paste having red, green and blue uniform rheological characteristics and without causing uneven coloration due to sagging in coating and the wind in drying by specifying the yield value and non-Newtonian viscosity index of a transparent resin composition contg. pigment. CONSTITUTION:This transparent resin composition contains pigment and is a colored paste for a color filter. The yield value s0 and the non-Newtonian viscosity index (n) are >=0.1Pa and . As the non-Newtonian viscosity index (n) is lowered, the film applied is smoothed immediately after coating, and the leveling performance is improved. The sagging in coating is reduced as the yield value sO is increased.

Abstract: PURPOSE:To obtain a color filter having a small depolarizing effect so that when this filter assembled in a liquid crystal display cell, such a product having high contrast and good display performance can be obtd. by using a coloring agent comprising an org. pigment and specifying the proportion of components except for the extender in the org. pigment. CONSTITUTION:The coloring agent consists of an org. pigment in which the proportion of components except for the extender is >=95wt.%. It is preferable that the proportion is >=97wt.%, and more preferably, >=99wt.%. The extender is a transparent or white pigment to be added to thin the color of the org. pigment and to control its color tone. For example, barium sulfate, heavy magnesium carbonate, soft magnesium carbonate, calcium carbonate, aluminum oxide, kaolinite, halloysite, muscovite, and talc are used. To obtain a color filter having a small depolarization effect, it is preferable to select such a pigment having =5wt.% extender, the extender can be removed in the production process of a paste, such as dispersing or filtering.

Abstract: PURPOSE:To obtain enough adhesion strength when a color filter and a counter electrode substrate are laminated by depositing a polyimide layer and an imido- modified silicone layer in this order to constitute a transparent protective film and processing the film into a desired pattern. CONSTITUTION:A transparent protective film is formed on a color layer, and further, a transparent electrode layer such as tin indium oxide is formed on the protective film. The transparent protective film is formed by depositing a polyimide layer and an imide-modified silicone layer in this order and processed into a desired pattern. The desired pattern means such a pattern that the transparent protective film is formed only on the required area such as the effective picture element area and that no film is formed on the edge part, side faces or back surface of the substrate. By processing the transparent protective film into this pattern, no transparent protective film is formed in unnecessary area. Thus, enoguh adhesion strength to laminate the color filter and the counter electrode substrate can be obtd.
