Abstract

A liquid crystal display having a positive A-film and a negative A-film between a top polarizer and a bottom polarizer to increase the viewing angle of the liquid crystal display by reducing or eliminating light leakage at voltage-off state when viewed from an oblique angle. Method of increasing the viewing angle of the liquid crystal display by reducing or eliminating light leakage at voltage-off stage when viewed from an oblique angle. The compensation is applicable to use with liquid crystal displays having a liquid crystal layer that is homogenously aligned at off-state when no voltage is applied to the liquid crystal layer, such as IPS and FFS mode liquid crystal displays.
