摘要： To provide a pigment dispersion excellent in dispersibility and spectral characteristics. The pigment dispersion at least includes: a dispersion medium; a compound represented by a general formula (1), the compound being dispersed in the dispersion medium; and a pigment having a quinacridone skeleton, the pigment being dispersed in the dispersion medium: General formula (1) in the general formula (1), R
1 and R
2 each independently represent a hydrogen atom, an alkyl group, an aryl group, or an aralkyl group.
