摘要

The present invention is a method for producing a pigment dispersion, a method for producing a curable composition, a method for producing a cured film, and a solid comprising a cured film, which can produce a pigment dispersion having a short treatment time and excellent storage stability. A method for manufacturing an image sensor, a method for manufacturing a color filter including a cured film, and a method for manufacturing an image display device including a cured film are provided. The method for producing a pigment dispersion of the present invention includes a step 1 of preheating a precursor composition containing a pigment, a dispersant, and an organic solvent and having a viscosity of 3 to 20 mPa · s at 25 ° C. And a step 2 of subjecting the precursor composition to a dispersion treatment by a bead mill while keeping the liquid temperature of the precursor composition at 40 ° C. or more and less than 60 ° C.
