A mesomorphic compound represented by the following formula (I):
wherein R1 and R2 respectively denote an alkyl group or alkoxy group each having 4 - 16 carbon atoms optionally substituted, halogen, -CN or -CF3. The mesomorphic compound is effective for providing a ferroelectric liquid crystal composition showing an improved low-temperature operation characteristic and a decreased temperature-dependence of response speed.
