ABSTRACT:
The invention lies in novel ferroelectric liquid crystal compounds particularly represented by the general formulae, having a good responsibility in relation to the applied electric field and a wide range of phase transition points inclusive of the room temperature so as to be useful alone as the liquid crystal material but also to be mixed with other liquid crystal compounds for expanding the phase transition points to a desired range and making the response speed of the liquid crystal composition faster. ##STR1## In the formulae, m and n are same or different with each other and represent an integral of 1-20.
