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), a VA-mode liquid-crystal cell (LC) disposed between the front-side polarizing element and the rear-side polarizing element, and a first retardation region (16) comprising one or more retardation layers between the rear-side polarizing element and the VA-mode liquid-crystal cell, wherein the first retardation region satisfies 0 nm≦Re(590)≦10 nm, and |Rth(590)|≦25 nm. Re(λ) means retardation (nm) in plane at a wavelength λ nm, and Rth(λ) means retardation (nm) along the thickness direction at a wavelength λ nm.
