Abstract:
1. 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 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 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.
