ABSTRACT:
A liquid crystal display includes a pair of substrates and a liquid crystal composition sealed between the substrates. The liquid crystal composition has a twist angle set within a range of 180-300 degrees and a retardation set within a range of 0.45-0.7, wherein when an electric field is applied, the liquid crystal display is in a dark state, while when the electric field is not applied, the liquid crystal display is in a bright state. A filter is laminated on the outside of the substrates, and it has a hue complementary to that of an image color of the liquid crystal display in the bright state.
