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

A color material wherein the color material is a lake color material of a combination of an acid dye and a polyaluminum chloride;

• a basicity of the polyaluminum chloride is 70% or more;
• and a value of a ratio (I4/I6) between an integral value (I4) of a peak corresponding to a four-coordinate aluminum in a solid-state 27Al-NMR spectrum of the lake color material and an integral value (I6) of a peak corresponding to a six-coordinate aluminum therein, is from 0 to 0.50.

A color filter comprising at least a transparent substrate and color layers disposed on the substrate, wherein at least one of the color layers contains a lake color material of a combination of an acid dye and a polyaluminum chloride;

• a basicity of the polyaluminum chloride is 70% or more;
• and a value of a ratio (I4/I6) between an integral value (I4) of a peak corresponding to a four-coordinate aluminum in a solid-state 27Al-NMR spectrum of the lake color material and an integral value (I6) Of a peak corresponding to a six-coordinate aluminum therein, is from 0 to 0.50.
