ABSTRACT:
An ON electric field for turning on (allowing light transmission) a liquid crystal optical device and an OFF electric field for turning off (shielding light) the liquid crystal optical device are selectively applied to a liquid crystal material of the liquid crystal optical device. The ON electric field is applied so as to obliquely align liquid crystal molecules with respect to substrates constituting the liquid crystal optical device, thereby obtaining an ON state. The ON electric field has an electric field for driving the liquid crystal molecules and a non-electric field for generating a state wherein no electric field is applied to the liquid crystal molecules. The OFF electric field has an electric field for homeotropically aligning the liquid crystal molecules with respect to the substrates.
