Abstract:
1. A color filter of a liquid crystal display device, comprising: a transparent substrate and colored pixels of red, blue and green which are formed on the transparent substrate, wherein the colored pixels are formed using a coloring composition including a transparent resin, an organic pigment having an average primary particle diameter of 5 nm to 40 nm and dispersed in the transparent resin, and a retardation-regulating agent dispersed in the transparent resin and containing a compound which is capable of increasing a retardation of the color filter in a thickness direction in a sufficient amount to minimize a difference in retardation among pixels, an optical retardation in a thickness direction of each of the colored pixels ranging between −10 nm and +16 nm and an optical retardation in a thickness direction of the green pixel ranging between −5 nm and +8 nm.
