Abstract:
1. A liquid crystal display comprising: a pair of polarizing films, a liquid crystal cell placed between the polarizing films, an optical compensatory film placed between at least one of the polarizing films and the liquid crystal cell, wherein the optical compensatory film comprises a first optically anisotropic layer and a second optically anisotropic layer, the liquid crystal cell is a bend alignment mode cell, and a voltage applied to the liquid crystal cell in white displaying state is 1V or less; wherein the optical compensatory film comprises a longitudinal direction and an in-plane refractive-index-reducing direction, wherein the optical compensatory film satisfies the following optical property within a plane which contains the normal line of the optical compensatory film and the direction of 45° inclined from the longitudinal direction toward the in-plane refractive-index-reducing direction: where Re(40°) is a retardation value measured in a direction inclined 40°, toward the plane of the optical compensatory film, from the normal line using light having a wavelength of 550 nm, and Re(−40°) is a retardation value measured in a direction inclined 40°, to the direction opposite to the direction of Re(40°), from the normal line using light having a wavelength of 550 nm.
