Patent ID: 7379131

Claim:
A liquid crystal display device comprising: two polarizer films having absorption axes being crossed normal to each other; a liquid crystal cell disposed between these two polarizer films, comprising a pair of substrate and a liquid crystal layer composed of liquid-crystalline molecules held therebetween, wherein liquid-crystalline molecules are oriented substantially normal to the substrates under non-operative state in the absence of applied external electric field; at least one layer of a first optically-anisotropic layer having an optically positive refractive anisotropy, being formed of rod-like liquid-crystalline molecules and having Re, defined below, falling within a range from 40 to 150 nm at visible light; and at least one layer of a second optically-anisotropic layer having an optically negative refractive anisotropy, and having Re ,defined below, of 10 nm or less and Rth, defined below, falling within a range from 60 to 250 nm at visible light: Re =( nx−ny ) × d (1) Rth ={( nx+ny )/2 −nz } × d (2) (where, nx denotes refractive index in the slow-axis direction in a layer plane; ny denotes in-plane refractive index in the direction normal to nx; nz denotes refractive index in the thickness-wise direction of a layer; and d denotes thickness of a layer).
