Color material dispersion liquid, color resin composition, color filter, liquid crystal display device, and light-emitting display device

A color material dispersion liquid including a color material, which is a salt-forming compound of an organic dye with a heteropolyoxometalate, a dispersant and a solvent, wherein the organic dye is at least one organic dye selected from the group consisting of a porphyrin dye, a tetraazaporphyrin dye, a phthalocyanine dye and a squarylium dye, and wherein the heteropolyoxometalate is a heteropolyoxometalate which has an oxidation-reduction potential larger than &#x2212;0.3 V relative to the silver/silver chloride electrode.

A color material dispersion liquid including a color material, a dispersant and a solvent, wherein the color material contains a compound which is represented by the following general formula (I) and which contains one or more structures selected from the following structures (i) and (ii); wherein (i) 'A' is an aliphatic hydrocarbon group containing two or more alicyclic hydrocarbon groups, containing a saturated aliphatic hydrocarbon group at a terminal position directly bound to 'N', and optionally containing O, S, N in a carbon chain, and (ii) at least one of Rto Ris a cycloalkyl group optionally containing a substituent group or an aryl group optionally containing a substituent group. 

This invention provides an azomethine compound that can realize a good coupling reaction and, at the same time, can significantly reduce the production cost of the azomethine compound, the azomethine compound comprising a pyridine ring bonded through a nitrogen atom to a 1H-pyrazolo[1,5-b][1,2,4]triazole ring. The azomethine compound is represented by formula (M-I): wherein Rrepresents a phenyl group or a naphthyl group optionally substituted by an alkyl group or a halogen; and Rand Reach independently represent a C2-4 (number of carbon atoms) alkyl group.
