Abstract:
The present invention relates to a VA-mode liquid-crystal display device comprising a front-side polarizing element (14), a rear-side polarizing element (12), and a VA-mode liquid-crystal cell (LC) 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 (24), a rear-side substrate (22), and a liquid-crystal layer (10) disposed between them, wherein the ratio of the member-contrast ratio (CRf) of the front-side substrate (22) to the member-contrast ratio (CRr) of the rear-side substrate, CRf/CRr satisfies 3≦CRf/CRr, and wherein the rear-side polarizing element (12) is directly stuck to the VA-mode liquid-crystal cell (LC).
