Patent ID: 7184112

Claim:
A liquid crystal display comprising a polarizing film A, a polarizing film B, and a vertical alignment mode liquid crystal cell provided between the polarizing films A and B, one or more cellulose ester films A only being provided between the polarizing film A and the liquid crystal cell, and one or more cellulose ester films B only being provided between the polarizing film B and the liquid crystal cell, wherein 31 nm≦Σ R 0 ≦120 nm, and 60 nm≦Rt≦300 nm, in which Σ R 0 =Σ R 0 (A)+Σ R 0 (B), and Σ Rt=Σ Rt (A)+Σ Rt(B), Σ R 0 (A) being the sum of retardation in plane of each of the cellulose ester films A, Σ R 0 (B) the sum of retardation in plane of each of the cellulose ester films B, Σ Rt(A) the sum of retardation in the thickness direction of each of the cellulose ester films A, and Σ Rt(B) the sum of retardation in the thickness direction of each of the cellulose ester films B, and wherein at least one of the cellulose ester films A and B is a mixed fatty acid cellulose ester film having a retardation in plane R 0 of from 31 to 120 nm, and a retardation in the thickness direction Rt of from 60 to 300 nm, in which R 0 is represented by the following formula (1) and Rt is represented by the following formula (2): R 0 =( nx−ny )× d formula (1) Rt ={( nx+ny )/2 −nz}×d formula (2) wherein nx is refractive index in plane of the film in a first direction giving a maximum refractive index, ny is refractive index in plane of the film in a second direction normal to the first direction, nz is refractive index in the thickness direction of the film, and d is thickness (nm) of the film, and wherein the mixed fatty acid cellulose ester film is provided on a first surface of the polarizing film, and a cellulose ester film is provided on a second surface of the polarizing film opposite the mixed fatty acid cellulose ester film, the stretching direction of the mixed fatty acid cellulose ester film being in accordance with that of the cellulose ester film provided on the second surface of the polarizing film.
