PIGMENT-DISPERSED LIQUID FOR COLOR FILTER, PIGMENT-DISPERSED RESIST COMPOSITION FOR COLOR FILTER, AND COLOR FILTER USING THEM

摘要

PROBLEM TO BE SOLVED: To provide a pigment-dispersed liquid and a pigment-dispersed resist composition for color filter, with which a color filter for color liquid crystal display having superior transparency, heat resistance and light resistance can be manufactured and which has superior preservation stability and developing property.;SOLUTION: The pigment-dispersed liquid is prepared by dispersing pigment (A), whose primary particle size is 10 - 80 nm into an organic solvent (C) in the presence of a dispersant (B). Therein, the average particle size of the pigment in the pigment-dispersed liquid is 80 nm or smaller and the particle size distribution of the pigment satisfies the expression (1): 5 (nm) ≤ (d₈₄-d₁₆) ≤ 50 (nm) (1). In the relation (1), d₈₄ represents the particle size (nm) of the point on a cumulative curve of the particle size distribution, whose cumulative amount becomes 84 wt.%, and d₁₆ represents the particle size (nm) of the point on the cumulative curve of the particle size whose cumulative amount becomes 16 wt.%.;COPYRIGHT: (C)2005,JPO&NCIPI
