    Abstract: A liquid crystal display comprises two parallel spaced substrates and a liquid crystal layer with negative dielectric anisotropy interposed between the substrates. The ratio d/p, the cell gap d between the substrates to the pitch p of the liquid crystal layer, is equal to or less than 0.3, and the retardation value Δn*d may be in the range of 0.25-0.4. In absence of electric field, the liquid crystal molecules are arranged vertically to the substrates, and when the sufficient electric field is applied, the liquid crystal molecules are parallel to the substrates and twisted by 90° from one substrate to the other.

    Abstract: Liquid crystal display devices include a vertically aligned liquid crystal cell having first and second surfaces that extend opposite each other and contain a liquid crystal material therein having negative dielectric anisotropy. First and second polarizers are attached to the first and second surfaces of the liquid crystal cell, respectively. A first a-plate compensation film and a first c-plate compensation film are provided. These films are disposed between the first surface of the liquid crystal cell and the first polarizer. The direction having a largest refractive index in the first a-plate compensation film is parallel to or perpendicular to a polarizing direction of the first polarizer. Moreover, a difference between a summation of a retardation (nx21−nza1)×da1 of the first a-plate compensation film, a retardation (nxc1−nzc1)×dc1 of the first c-plate compensation film and a retardation of the first and the second polarizers and a retardation due to birefringence of the liquid crystal cell is equal to or less than 15% of the retardation value due to birefringence of the liquid crystal cell.
