WebbAntiferroelectric liquid crystals (AFLCs) are a type of liquid crystals (SmC*A ) [6-10] in which spontaneous polarization has been created on different layers due to the helical superstructure. The c-director of the adjacent layers of AFLCs is nearly antiparallel to each other because of its anticlinic nature.
