Abstract
Disclosed are a chiral compound, a liquid crystal composition containing the chiral compound, an optically anisotropic body and a liquid crystal display device. The structural formula of said chiral compound is as represented by the following formula I: The chiral compound has a high HTP value and a good solubility; a highly helical, twisted liquid crystal composition can be prepared by adding a small amount of the chiral compound; reducing the addition amount of the chiral compound can reduce the negative effect of the chiral compound on the parameters of the liquid crystal composition; under the conditions of the same addition ratio and the same helical pitch, the chiral compound can reduce the response time of the liquid crystal composition; in addition, the chiral compound has a simple structure and greatly reduces the synthesis cost.
