Abstract
Provided is a pigment dispersion composition suitable for a colored curable composition which enables retaining adhesion capability of a colored pattern and inhibiting the generation of residues, even when a relatively severe development condition is employed. Furthermore, a red colored composition capable of forming a red colored thin film with excellent spectral characteristics. The pigment composition contains an azo pigment represented by the following Formula (1); at least one of acidic functional group-containing organic pigment derivative, anthraquinone derivative, and triazine derivative; and a dispersant. The red colored composition contains a red pigment; a yellow pigment; and a dispersant, in which specific spectral characteristics are satisfied when a colored transmitting film having a thickness of 0.6 μm is formed using the red colored composition.
