    • 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.
