Abstract: A liquid crystal composition including a dioxolane compound represented by the general formula (G1) as a chiral agent is provided. In the general formula (G1), R1 and R2 individually represent any of hydrogen, an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 20 carbon atoms, an aryl group having 6 to 12 carbon atoms, and an alkyl group having 1 to 20 carbon atoms and having a phenyl group as a substituent; R1 and R2 may be bonded to each other to form a ring; R3 and R4 individually represent any of hydrogen, an alkyl group having 1 to 6 carbon atoms, and a cycloalkyl group; and R5 to R40 individually represent any of hydrogen, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, and an aryl group having 6 to 12 carbon atoms.
