(57) [Problem] To provide an optically active liquid crystal compound capable of suppressing an increase in viscosity of a liquid crystal composition and imparting excellent twist alignment performance with a small amount of addition. SOLUTION: R 1- (A 1 ) m -A 2 -CF = CF-A 3 - (A 4) n -B- (CH 2) p -C * HX-R 2. R 1 and R 2 each represent an alkyl group having 1 to 10 carbon atoms such as A 1 to A 4 Is 1,4-phenylene group or trans-1,4-cyclohexylene group; B is carbonyloxy group; m, n Is 0 or 1, and p is an integer of 0 to 5. |
