ABSTRACT:
A manufacturing method includes a process of once heating a liquid crystal material to a temperature at which an isotropic phase appears therein and then cooling the liquid crystal material, the liquid crystal material being a ferroelectric liquid crystal or antiferroelectric liquid crystal, to be performed under an applied AC electric field which generates an electroclinic effect in a temperature range of from a temperature 20.degree. C. above a phase transition temperature at which a transition in phase occurs from a smectic A phase to a chiral smectic C phase to a temperature 20.degree. C. below the phase transition temperature.
