PROBLEM TO BE SOLVED: To obtain a new optically active compound which can be added to a liquid crystal material to maintain a low viscosity and give a desired spiral pitch, and a liquid crystal composition containing the compound. SOLUTION: The optically active compound is represented by formula (1) [R<SB>1</SB>and R<SB>2</SB>are each independently a 1 to 10C alkyl; the ring A is trans-1,4- cyclohexylene or 1,4-phenylene; (n) and (m) are each independently an integer of 0 to 2; Z<SB>1</SB>to Z<SB>6</SB>are each independently H or F; * exhibits an asymmetric carbon atom].
