Abstract
A black matrix of resin, as a constituent member of a color filter for, e.g., displays of color TV sets and personal computers, method for producing the black matrix of resin, method for producing a color filter using the same black matrix, and liquid crystal element using the color filter produced by the same method. The method of the present invention for producing a black matrix of resin is characterized by comprising forming a resin on a substrate, exposing the above resist at an exposure of 14.0 to 70.0 mJ/cm2 via a photomask and developing the exposed resist to produce a pattern.
