Abstract
A liquid crystal element includes a liquid crystal having a molecular orientation varying according to an applied voltage, first upper and lower electrodes which are opposed in plane to each other and between which the liquid crystal is interposed, and second upper and lower electrodes which are not opposed in plane to each other and between which the liquid crystal is interposed. Phasic variations of the liquid crystal element are obtained by means of a first electric field which is impressed on the liquid crystal by applying a first voltage between the first upper and lower electrodes and a second electric filed which is generated by applying between the second upper and lower electrodes a second voltage which differs from the first voltage.
