Abstract
The present invention relates to a colorant, a colored resin composition comprising the colorant, and a color filter prepared using the colored resin composition. A novel reddish yellow pigment may be used in combination with a green pigment and a yellow pigment in order to reduce the imbalance of the intramolecular polarization of the green pigment and/or the yellow pigment in the colorant. As a result, a color filter comprising a colored layer in which a light leakage phenomenon, caused by an electric field distortion, is reduced.
