Patent ID: 8305525

Claim:
A liquid crystal display device comprising: a liquid crystal layer; and a first polarizing plate and a second polarizing plate that are placed with the liquid crystal layer sandwiched therebetween and that each include a polarizing film and a protective film provided on at least an outer surface of the polarizing film, in which the first polarizing plate is placed on a light source side and the second polarizing plate is placed on a view side, wherein the protective film on the view side of the second polarizing plate includes a transparent support satisfying the following Expression (1) and an optically anisotropic layer having a λ/4 function, and Rth of the protective film on the view side of the second polarizing plate is |Rth|≦20, 0 ≦|Re (550)|≦10 (I) wherein Re(550) denotes an in-plane retardation value (unit: nm) at a wavelength of 550 nm; and Rth denotes a retardation value (unit: nm) in a film thickness direction at a wavelength of 550 nm, and wherein the in-plane retardation value and the retardation value in the film thickness direction are defined by the following expressions with respect to an object: Re =( nx−ny )× d Rth =(( nx+ny )/2 −nz )× d wherein nx denotes a refractive index in a direction of a slow axis in a plane of the object; ny denotes a refractive index in a direction orthogonal to nx in the plane; nz denotes a refractive index in a direction orthogonal to nx and ny; and “d” denotes a film thickness of the object in the direction of nz.
