METHOD FOR PRODUCING GREEN PIGMENT DISPERSION FOR COLOR FILTER, GREEN PIGMENT DISPERSION FOR COLOR FILTER PRODUCED BY THE SAME, GREEN-COLORED RESIST FOR THE COLOR FILTER, COLORED LAYER, COLOR FILTER, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a green pigment dispersion element for a color filter which is superior in long-term storage stability and has viscosity increase with time and deterioration in contrast ratio suppressed, to provide a green-colored resist containing the dispersion element, and to provide a color filter superior in oblique visibility and a liquid crystal display device.;SOLUTION: A method for producing the green pigment dispersion element for a color filter is characterized in that a process comprising kneading a mixture including a green pigment containing a halogenated zinc phthalocyanine pigment, a yellow pigment, a transparent resin and a resin-type dispersant by a roll mill into a sheet-like material is repeated a plurality of times, and then green co-chips obtained by crushing the sheet-like material are dissolved into an organic solvent.;COPYRIGHT: (C)2011,JPO&INPIT
