The present invention employs ester compounds such as butyl acetate, oleyl acetate and the like that are typically employed in solvents and other applications as an agent for improving the fluidity of a pigment dispersion liquid. The pigment composition of the present invention includes a pigment and the aforementioned ester compound as essential components. A pigment dispersion liquid in which the present invention's pigment composition is dispersed in a solvent or the like demonstrates a great improvement in pigment dispersibility and dispersion liquid flow properties. When the present invention's pigment composition and pigment dispersion liquid are employed in a color filter, it is possible to obtain a uniform paint film having high contrast.
