Claim:
A liquid crystal display comprising at least a first polarization film, a first retardation region, a second retardation region, a liquid crystal layer, a liquid crystal cell composed of a pair of substrates with the liquid crystal layer being interposed between the substrates, and a second polarization film disposed in this order, liquid crystal molecules of the liquid crystal layer being aligned in parallel with surfaces of the substrates at the time of dark state, wherein an in-plane retardation (Re) of the first retardation region is 70 nm to 330 nm, an Nz value of the first retardation region defined as Nz=Rth/Re+0.5 using the in-plane retardation (Re) and retardation (Rth) of a thickness direction of the first retardation region is greater than 0 and less than 0.4, an in-plane retardation of the second retardation region is equal to 50 nm or less and an optical axis is simultaneously not included in the in-plane of the second retardation region, a retardation of a thickness direction of the second retardation region is 10 nm to 140 nm, a slow axis of the first retardation region is orthogonal to a transmissive axis of the first polarization film and the transmissive axis of the first polarization film is simultaneously in parallel with a slow axis direction of the liquid crystal molecules at the time of dark state, each of the first and second polarization films has at least a protective film on a plane close to the liquid crystal layer, in which the corresponding protective film may act as another layer, and the corresponding protective film is a cellulose acylate film which meets the formulae (I) and (II) below: 0 ≦Re (630) ≦10, and, | Rth (630) |≦25 (I) | Re (400) − Re (700) |≦10, and, | Rth (400) − Rth (700) |≦35 (II) wherein Re (λ) represents an in-plane retardation (nm) in the wavelength λnm, and Rth (λ) represents a retardation (nm) of a film thickness direction in the wavelength λnm.
