The invention discloses a chiral compound, a liquid crystal composition containing the chiral compound, an optical anisotropy, and a liquid crystal display device. The structural formula of the chiral compound is shown in the following formula I: I; Chiral compounds have a high HTP value and good solubility. By adding a small amount of chiral compounds, a highly helical twisted liquid crystal composition can be prepared, reducing the amount of chiral compounds added, and reducing chiral compounds. Negative effects on the parameters of the liquid crystal composition. Under the conditions of the same addition ratio and the same pitch, the chiral compound can reduce the response time of the liquid crystal composition, and the structure of the chiral compound is simple, which greatly reduces the synthesis cost. |
