Abstract

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 R2 to R5 is a cycloalkyl group optionally containing a substituent group or an aryl group optionally containing a substituent group.
