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 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 200 nm<Re<500 nm and Re<Rz, when nx and ny are main refractive indexes in an intra-plane and nz is a main refractive index in a direction of the thickness, and further there are relations of nx>ny, (nx-ny)d=Re and (nz-nx)d=Rz. The laminated polarizing plate consists of a laminated body of the phase difference plate and a polarizing plate.
