ABSTRACT:
A liquid crystal composition includes at least one fluorine-containing mesomorphic compound (a) having a fluorocarbon terminal portion and a hydrocarbon terminal portion, and at least one optically active compound (b) having an optically active cyclic group and a terminal alkyl group free from a perfluorocarbon atom. The compound (a) and the compound (b) are mutually soluble readily to form a homogeneous liquid crystal composition. The liquid crystal composition shows a layer structure of so-called bookshelf or a layer structure having a small inclination angle (closer to bookshelf structure). The liquid crystal composition is useful in improving response characteristics and display characteristics, particularly a contrast ratio, of a liquid crystal device using the liquid crystal composition.
