Patent ID: 7872714

Claim:
A liquid crystal cell substrate with a color filter having a transparent substrate and a color filter having three color regions: blue, green and red, where a retardation value Rth in the thickness direction, which is represented by the following formula (1) in the blue region, the green region and the red region of the color filter, satisfies the following formula (2) or (3): Rth =[{( nx+ny )/2}− nz]×d Formula (1) Rth ( B )> Rth ( G )> Rth ( R ) Formula (2) Rth ( B )< Rth ( G )< Rth ( R ) Formula (3) wherein nx and ny represent the in-plane refractive index of each color region (provided that nx ≧ny), nz represents the refractive index in the thickness direction of each color region, and d represents the thickness of each color region, Rth(B) represents the retardation value in the thickness direction for a wavelength of 450 nm in the blue region, Rth(G) represents the retardation value in the thickness direction for a wavelength of 546 nm in the green region, and Rth(R) represents the retardation value in the thickness direction for a wavelength of 633 nm in the red region.
