(57) [Summary] [Purpose] The temperature range of the chiral smectic phase is wide, Provided are a liquid crystal composition having excellent response in a low temperature range, low response speed temperature dependence, and excellent display quality, and a liquid crystal element using the liquid crystal composition. A liquid crystal compound having an optically active group in which a fluorine atom is directly bonded to an asymmetric carbon atom and having an ester bond, the liquid crystalline compound containing the optically active group as a carboxylic acid component of the ester bond. And a liquid crystal compound containing the optically active group as an alcohol component of the ester bond, and a liquid crystal device containing the liquid crystal composition. |
