Abstract

This invention provides a resin black matrix with a light- shading agent dispersed in a resin, comprising carbon black satisfying at least one of the following features of (A) to (D), as the light-shading agent: (A) 6.5 or less in pH (B) 0.001 < [COOH] in the carboxyl group concentration [COOH] on the surface, as a molar ratio per all carbon atoms (C) 0.001 < [OH] in the hydroxyl group concentration [OH] on the surface, as a molar ratio per all carbon atoms (D) 0.001 < [SO3H] in the sulfonic acid group concentration [SO3H] on the surface, as a molar ratio per all carbon atoms. The present invention also provides a black paste with a light-shading agent dispersed in a resin or its precursor solution, comprising carbon black satisfying at least one of the above features of (A) to (D) as, the light-shading agent. The third aspect of the present invention is a color filter, comprising the resin black matrix. The color filter of the present invention is, by using the carbon black, high in light-shadability and can display images with excellent quality when set in liquid crystal display devices.
