Δn=nXY−nZ (1) Rth={(Nx+Ny)/2−Nz}×d (2)
摘要:
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.

摘要:
A color filter is provided with red, green and blue color filter segments. When chromaticity coordinates (x, y) in a chromaticity diagram of XYZ color specification system are measured with the color filter being sandwiched between two polarizers, a chromaticity (xp, yp) of parallel-transmitted light and a chromaticity (xc, yc) of orthogonal-transmitted light satisfy the following formula (1): Δxy=[(xp−xc)2+(yp−yc)2]1/2
