The present invention relates generally to the field of liquid crystal display devices and more particularly to a liquid crystal display device operating in vertically aligned mode (VA-mode) in which liquid crystal molecules having a negative dielectric anisotropy are aligned generally perpendicularly to a panel surface of the liquid crystal display. A liquid crystal display according to the invention comprises a liquid crystal cell (
6
) of a vertical alignment mode, at least one polarizer (
2, 10
) arranged on each side of the liquid crystal cell, and at least one compensating structure (
3, 7
) disposed between the liquid crystal cell and at least one of the polarizers. The polarizers have transmission axes (
11, 18
) which are perpendicular to each other.
