Abstract:
The present invention addresses the problem of providing: a pigment dispersion liquid with which an optical filter layer having the functions of both a color filter and a near-infrared cut filter can be formed by performing a development step once, and with which a thin filter achieved by using a single-layer configuration instead of a conventional two-layer configuration can be fabricated; and a colored resin composition containing the pigment dispersion liquid. The present invention provides a pigment dispersion liquid containing one or more organic color pigments selected from the group consisting of pigment red, pigment green, pigment blue, pigment yellow, and pigment violet, an infrared absorbing dye having a maximum absorption wavelength in a wavelength range of 750-2000 nm, and an oil-soluble organic solvent or an aqueous medium, and a colored resin composition containing the dispersion liquid.
