VA-mode liquid-crystal display device

A VA-mode liquid-crystal display device comprising at least a front-side polarizing element, a rear-side polarizing element, and a VA-mode liquid-crystal cell disposed between the front-side polarizing element and the rear-side polarizing element;

• wherein the VA-mode liquid-crystal cell comprises a front-side substrate, a rear-side substrate, and a liquid-crystal layer disposed between them,
• wherein the ratio of the member-contrast ratio (CRf) of the front-side substrate to the member-contrast ratio (CRr) of the rear-side substrate, CRf/CRr satisfies the following relational formula:
• 3≦CRf/CRr,
• wherein the rear-side substrate and the front-side substrate include any constitutive member(s) of the VA-mode liquid-crystal cell disposed on the respective substrates,
• wherein the rear-side polarizing element is directly stuck to the VA-mode liquid-crystal cell, and
• wherein the VA-mode liquid-crystal display device further comprises a retardation region comprising one or more retardation layers between the front-side polarizing element and the VA-mode liquid-crystal cell, and wherein the retardation region satisfies the following formulae:
• 30 nm≦Re(550)≦90 nm,
• 170 nm≦Rth(550)≦300 nm, and
• Δnd(550)−70≦Rth(550)≦Δnd(550)−10,
• in which d means the thickness (nm) of the liquid-crystal layer of the VA-mode liquid-crystal cell;
• Δn(λ) means the refractivity anisotropy of the liquid-crystal layer of the VA-mode liquid-crystal cell at a wavelength λ;
• Δnd(λ) means the product of Δn(λ) and d;
• and Rth(λ) means the retardation (nm) in the thickness direction of the retardation region at a wavelength λ.
