Abstract
A liquid crystalline compound represented by the following general formula: ##STR1## where m and l represent individually integers within a range: 6.ltoreq.m.ltoreq.14 and 1.ltoreq.l.ltoreq.5, the symbol * represents an asymmetric carbon atom and the compound is required to be optically active. The compound can induce the twisting arrangement when added to the TN system or phase transition type liquid crystal mixture, as well as can improve the spontaneous polarization as the index of the ferroelectric property when added to the SmC* liquid crystal mixture.
