Patent ID: 7948583

Claim:
A coloring composition for a color filter of a liquid crystal display device, the color filter including colored pixels of at least two colors, the coloring composition for colored pixels of one of the colors comprising: 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 a retardation of the color in a thickness direction in a sufficient amount to minimize a difference in retardation among colored pixels, wherein a contrast C represented from the following equation is not less than 3000, C=Lp/Lc wherein Lp is the luminance of light measured by means of a luminance meter as the light is passed through a laminated structure consisting of a pair of polarizing plates with a coated film of the coloring composition of single color deposited on a transparent substrate being sandwiched therebetween after a backlight is applied to one of the polarizing plates and permitted to emit from the other of the polarizing plates under a condition wherein axes of these polarizing plates are parallel with each other; and Lc is the luminance of light measured under the same conditions as described above except that axes of these polarizing plates are orthogonal to each other.
