ABSTRACT:
A liquid crystal device can be driven by application of a unipolar electric field to a ferroelectric liquid crystal layer. Without application of an electric field, isotropic characteristics are observed because of a spiral arrangement of the liquid crystal molecules. Under the application of an electric field, a birefringence is observed because of liquid crystal molecules being aligned in one direction. The device can be driven by applying an electric field in one direction and removing the electric field.
