Its manufacturing method, color filter, as well as organic light-emitting display device and liquid crystal display device and color filters for red-sensitive resin composition

摘要

Disclosed are: a red pigment dispersion liquid for a color filter that especially has achieved high luminance and higher contrast ratio; and a red photosensitive resin composition for a color filter. Specifically disclosed are: a red pigment dispersion liquid for a color filter, which contains a diketopyrrolopyrrole-based red pigment, a sulfonated derivative of a yellow pigment, a pigment dispersant that is a block copolymer containing a salt of a tertiary amine or a quaternary ammonium salt, and a solvent; and a red photosensitive resin composition for a color filter, which contains the pigment dispersion liquid.
