Novel ferroelectric liquid crystal compounds showing three stable liquid crystal states so as to give particular optical response wave shape as well as particular optical and electric responses to impressed voltage of triangle wave shape in comparison with usual ferroelectric liquid crystals of bistable phase, whereby it is possible to provide electrooptical devices having larger picture area at lower cost. Typical compounds are represented by ##STR1## wherein n is an integer of 3-18 and m is an integer of 5-12.
