Abstract
While light of R, G and B is switched from one to another and directed to a plurality of light shutter elements made of PLZT, a voltage is applied in accordance with image data between individual electrodes for the respective light shutter elements and a common electrode for all the light shutter elements. While a half-wave voltage Vr for light of R is applied to the individual electrodes, the voltage applied to the common electrode is altered to 0V, Vr-Vg and Vr-Vb in synchronization with switch of the three primary colors so that half-wave voltages for the respective colors can be applied to the light shutter elements.
