Abstract

Provided is a pigment dispersion having excellent depolarizing properties and capable of forming a high-contrast red picture element. The present invention relates to a pigment dispersion which is composed of a pigment, a solvent and a dispersant wherein upon formation of a red pigment element over a glass substrate by using a colored resin composition containing the pigment dispersion, Contrast C, that is, a ratio B/A (light intensity B when the substrate is sandwiched between two polarizing plates, the polarizing plates are disposed in parallel to light intensity A when they are disposed at right angles), as measured by a brightness photometer, satisfies the following equation: C ≥4000x-2000 in which x means a chromaticity of a transmitted light, as measured by a spectrophotometer, when exposed to an illuminant C, and the pigment contains an anthraquinone red pigment, preferably C.I. Pigment Red 177 and an azo yellow pigment, preferably C.I. Pigment Yellow 150 and has a particle size within a range of from 30 to 500 nm. The present invention further relates to a process for preparing the pigment dispersion, which comprises subjecting a mixture of the pigment, solvent and dispersant to dispersing treatment with beads having an average particle size of from 30 to 500 μm.
