发明名称
摘要 A liquid-crystal display device comprising a liquid-crystal cell comprising a liquid-crystal layer that aligns vertically to the substrate thereof in the black state, first and second polarizing elements that are disposed to sandwich the liquid-crystal cell therebetween so that their absorption axes are orthogonal to each other, a retardation film A and a retardation film B, wherein the retardation films A and B are equivalent to each other in terms of retardation in plane at a wavelength of 548 nm, Re(548), and retardation along thickness direction at a wavelength of 548 nm, Rth(548) thereof, but differ from each other in terms of the wavelength dispersion characteristics of retardation in plane Re and/or retardation along thickness direction Rth thereof in a visible light region, is disclosed.
