<p>PROBLEM TO BE SOLVED: To provide a method for producing a pigment dispersed colored paste for a color filter, having a small composition dispersion and excellent pigment dispersibility without discharging waste liquid containing a pigment, a polymer, etc., and to obtain a color filter having an uniformity in a film thickness of picture elements and excellent flatness by using the colored paste. SOLUTION: In a batch type production process in which a pigment for coloring in a solution to be treated containing the pigment for coloring, a dispersant and a solvent is dispersed by using a wet type disperser to give a pigment dispersion and a pigment dispersed paste is produced from the pigment dispersion, this method for producing the colored paste for a color filter is characterized in that a process in which a fixed amount of the solvent is prepacked into the disperser and then the solution to be treated obtained by subtracting the packed solvent from the composition of the pigment dispersion is introduced into the disperser is used.</p> |
