ABSTRACT:
A vertically-aligned liquid crystal display device includes a liquid crystal layer sandwiched between a pair of glass substrates, wherein a retardation of the liquid crystal layer is optimized in a range between 80 nm and 400 nm. Further, the use of retardation films adjacent to the liquid crystal layer and its optimization are also disclosed.
