Abstract
Disclosed is a VA-mode liquid-crystal display device wherein the total of retardation along the thickness-direction at a wavelength of 550 nm of the color filter layer, RthCF(550), and retardation along the thickness-direction at a wavelength of 550 nm of the whole rear-side retardation region, Rthrear(550), satisfies following formula (I): (I) |RthCF(550)+Rthrear(550)|≦90 nm.
Claims18
A VA-mode liquid-crystal display device comprising:
- a front-side polarizing element,
- a rear-side polarizing element,
- a liquid-crystal layer disposed between the front-side polarizing element and the rear-side polarizing element,
- a color filter layer disposed between the liquid-crystal layer and the rear-side polarizing element, and
- a rear-side retardation region composed of one or more retardation layers disposed between the rear-side polarizing element and the color filter layer;
- wherein the total of retardation along the thickness-direction at a wavelength of 550 nm of the color filter layer, RthCF(550), and retardation along the thickness-direction at a wavelength of 550 nm of the whole rear-side retardation region, Rthrear(550), satisfies following formula (I):
- |RthCF(550)+Rthrear(550)|≦90 nm. (I)
