Zusammenfassung: | Provided are a liquid crystal molecule orientation control method and a liquid crystal device which render it possible to change the orientation of liquid crystal molecules without using an electric field. In controlling the orientation of liquid crystal molecules 103a, which are contained in a liquid crystal material 103 sandwiched between alignment films 104, by the liquid crystal molecule orientation control method, an ultrasonic wave is generated in a piezoelectric material 102 so as to propagate to the liquid crystal material 103, and static pressure is generated in accordance with the ultrasonic wave, with the result that the orientation is changed in accordance with the magnitude of the static pressure. |
