1. A color material dispersion liquid for color filters, comprising: (A) a color material, (B) a dispersant and (C) a solvent, wherein the color material (A) contains (A-1) a color material represented by the following general formula (I) and (A-2) a metal lake color material of a rhodamine-based acid dye:wherein “A” is an “a”-valent organic group in which a carbon atom directly bound to “N” has no π bond, and the organic group is an aliphatic hydrocarbon group having a saturated aliphatic hydrocarbon group at least at a terminal position directly bound to “N”, or an aromatic group having the aliphatic hydrocarbon group, and O, S, N can be contained in a carbon chain of the organic group; Bc− is a “c”-valent polyoxometalate anion; each of Ri to Rv is independently a hydrogen atom, an alkyl group which can have a substituent group, or an aryl group which can have a substituent group; Rii and Riii can be bound to form a ring structure, and/or Riv and Rv can be bound to form a ring structure; Ar1 is a divalent aromatic group which can have a substituent group; a plurality of Ris can be the same or different; a plurality of Riis can be the same or different; a plurality of Riiis can be the same or different; a plurality of Rivs can be the same or different; a plurality of Rvs can be the same or different; a plurality of Ar1s can be the same or different;
“a” and “c” are each an integer of 2 or more, and “b” and “d” are each an integer of 1 or more; “e” is 0 or 1, and there is no bond when “e” is 0; and a plurality of “e”s can be the same or different.
