Liquid crystal compound comprising two condensed and substituted rings |
abstract |
A new liquid crystal compound comprises two condensed and substituted rings. The ring preferably is a five-membered heterocyclic ring. The heterocyclic ring is preferably condensed with benzene ring or an aromatic six-membered heterocyclic ring. The benzene ring or the aromatic six-membered heterocyclic ring is preferably substituted with a group comprising a cyclic structure and a chain structure. The liquid crystal compound is advantageously used in preparation of a thin phase retarder, such as a wide-ranged λ/4 plate, which gives inverse wavelength distribution. The phase retarder can be easily produced according to a simple process by using the new liquid crystal compound. |
