(57) [Abstract] [Purpose] To provide an optically active ester compound necessary for the production of a ferroelectric liquid crystal substance having high light resistance. [Structure] [Chemical 1] (In the formula, R * represents an optically active 2-methylbutyl group or an optically active 1-methylalkyl group having 4 to 12 carbon atoms) The liquid crystalline compound obtained from the optically active p-bromomethylbenzoic acid alkyl ester represented by the formula (1) was a ferroelectric liquid crystal stable to light. |
