ABSTRACT:
A coloring composition for a color filter includes a transparent resin, an organic pigment dispersed in the transparent resin, and a retardation-regulating agent dispersed in the transparent resin and containing a compound which is capable of increasing retardation in the thickness direction to minimize the difference in retardation among colored pixels. A color filter having colored pixels formed on a transparent substrate uses this coloring composition. A liquid crystal display device using this color filter may have improved black image quality and contrast.
