Claim:
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 disposed between the first polarizing element and the liquid-crystal cell and satisfying the following conditions (I) and (II), and a retardation film B disposed between the second polarizing element and the liquid-crystal cell and satisfying the following conditions (I) and (II), 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: 30 nm≦ Re (548)≦80 nm, (I) 70 nm≦ Rth (548)≦140 nm, (II) where Re(λ) [nm] means retardation in plane of the film measured at a wavelength λ [nm]; and Rth(λ) [nm] means retardation along thickness direction of the film measured at a wavelength λ [nm]; and wherein retardation in plane Re of the retardation film A satisfies any of the following conditions (III) to (V), and retardation in plane Re of the retardation film B satisfies any of the following conditions (III) to (V) other than that which Re of the retardation film A satisfies: Re (446)/ Re (548)<1 and Re (628)/ Re (548)>1, (III) Re (446)/ Re (548)>1 and Re (628)/ Re (548)<1, (IV) | Re (446)− Re (628)|/ Re (548)<0.03.
