METHOD FOR MANUFACTURING COLOR FILTER INK, COLOR FILTER INK, COLOR FILTER, IMAGE DISPLAY DEVICE, AND ELECTRONIC DEVICE

摘要

A method for manufacturing color filter ink is provided to ensure excellent discharge stability, dispersion stability of pigment, and contrast, and to improve the uniformity between objects by suppressing color unevenness, and concentration unevenness. A method for manufacturing color filter ink adapted to be used to manufacture a color filter by an inkjet method comprises: dispersing a dispersing agent in a solvent to obtain a dispersing-agent-dispersed liquid by agitating a mixture of the dispersing agent, a thermoplastic resin and the solvent; performing a fine dispersion treatment to obtain a pigment dispersed material by adding a pigment to the dispersing-agent-dispersed liquid and by adding inorganic beads to the dispersing-agent-dispersed liquid in multiple stages; and mixing the pigment dispersed material with a curable resin.
