Abstract:
1. A liquid crystal display device, comprising: a first polarizer; a liquid crystal cell; a second polarizer having an absorption axis azimuth that is orthogonal, in a plan view of a display surface of the liquid crystal cell, to that of the first polarizer, in this order; and a retardation film provided at least one of between the first polarizer and the liquid crystal cell, and between the second polarizer and the liquid crystal cell, wherein the retardation film is a reverse wavelength dispersion-type biaxial retardation film having an in-plane slow axis that is orthogonal, in a plan view of the display surface, to an absorption axis of a polarizer on the same side with respect to the liquid crystal cell, and satisfying equations (1) to (4) below, and the liquid crystal cell is a vertical alignment liquid crystal cell having a pair of transparent substrates, and provided therebetween a liquid crystal layer and at least blue, green and red color filter layers that separate three respective colors of blue, green and red, and satisfying equations (5) and (6) below, where in equations (1) to (4), R Rth(B), Rth(G) and Rth(R) denote, respectively, thickness-direction retardations of the retardation film at wavelengths 450 nm, 550 nm and 650 nm, and in equations (5) and (6), Rth_LC(B), Rth_LC(G) and Rth_LC(R) denote, respectively, thickness-direction retardations of the liquid crystal cell at wavelengths 450 nm, 550 nm and 650 nm.
