A liquid crystal compound comprising the following general formula (1): <IMAGE> (1) where i, j and k individually represent an integer within a range: 1</=i</=8, 0</=j</=7, 4</=k</=14, Ar1 represents <IMAGE> <IMAGE> +TR <IMAGE> *represents an asymmetric carbon and the compound is required to be optically active. The compound can provide various merits as the chiral substance such as satisfactory optical rotation, capability of inducing twisted arrangement when added to the TN system or phase transition system liquid crystal mixture, and of enlarging the liquid crystal temperature range when added to SmC* liquid crystal mixture.
