    • A pigment dispersion liquid excelling in depolarization characteristics and capable of forming red pixels of high contrast. There is provided a pigment dispersion liquid comprising a pigment, a solvent and a dispersant, characterized in that when red pixels are formed on a glass substrate with the use of a colored resin composition containing the pigment dispersion liquid and when the substrate is interposed between two polarizing plates and measured by means of a color brightness meter, the contrast (C) being the ratio of light intensity (B) exhibited at arranging of the polarizing plates in parallel relationship to light intensity (A) exhibited at arranging in orthogonal relationship, B/A, satisfies the relationship C >= 4000x - 2000 wherein x is the value of chromaticity of transmitted light with light source (C) as measured by means of a spectrophotometer, and that 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 diameter ranging from 30 to 500 nm. There is further provided a process for producing the pigment dispersion liquid, characterized in that a mixture of pigment, solvent and dispersant is dispersed by the use of beads of 30 to 500 mum average grain diameter.
