PROBLEM TO BE SOLVED: To provide a liq. crystal display device with excellent visibility as for contrast, monochromatic display or the like in a broad visual angle by providing a thinner phase difference plate which effectively compensates for a double refractivity caused by a liq. crystal cell. SOLUTION: A liq. crystal display device is constituted by a phase difference plate, a laminated polarizing plate, and the phase difference plate and/or the polarizing plate at least on one side of a liq. crystal cell. The phase difference plate satisfies an expression Re: (nx-ny)d<20 nm and an expression Rz: (nz-nx)d<1000 nm, where nx and ny are refractive indexes in an intra-plane, nz is a main refractive index in a direction of the thickness, nx>ny and d is thickness. The laminated polarizing plate consists of a laminated body of the phase difference plate and a polarizing plate. |
