Abstract
In a light shutter device in which multiple light shutter elements are located on a substrate made of PLZT, and the ON/OFF control of light is carried out by having an electrical field operate on each light shutter element from a pair of electrodes, the cross-talk phenomenon occurs among adjacent elements on the PLZT substrate, i.e., the elements ( ), ( ) and ( ). In order to effectively prevent such cross-talk, driving is carried out such that an electrical field does not operate on such elements simultaneously as a practical matter. In other words, the one line cycle is divided into periods (a) and (b), and the element ( ) is turned ON during the period (a) while the other elements ( ) and ( ) are turned ON during the period (b). Through this operation, a light shutter device in which each element has a stable amount of pass-through light may be obtained.
