摘要:
A liquid crystal display comprising a first polarization film, a first retardation region, a second retardation region, a liquid crystal layer, a liquid crystal cell, 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 Re of the first retardation region is 70 nm to 330 nm, Nz value of the first retardation region is greater than 0 and less than 0.4, Re 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, Rth 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 that 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, 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).
