Liquid crystal compounds and liquid crystal compositions containing them (Liquid crystal compounds and liquid crystal compositions containing the same)

摘要

Novel liquid crystalline compounds of formula (1) and liquid crystal compositions containing them.;Wherein R_OneIs an alkyl having 1 to 12 carbon atoms and is one CH₂Y is a hydrogen atom or an alkoxy group having 1 to 5 carbon atoms, 1 and m are each independently 0 or 1, and X is a hydrogen atom or a fluorine atom, n and p are each independently an integer of 0 to 10; when p is 0, n is 1 or more; when Y is an alkoxy group, X is a fluorine atom and p is 0;;It is possible to provide a liquid crystal composition having a high transparency point suitable for use in a liquid crystal display element and having a viscosity decreasing action and a novel liquid crystalline compound useful as a component of the liquid crystal composition.
