ABSTRACT:
An electro-optical modulating system comprised of a liquid crystal device with a plurality of pixels each comprising a pair of opposite electrodes, and an optical modulating substance assuming a first molecular orientation state and a second molecular orientation state between the electrodes. The system further comprises voltage application circuit for applying to a pixel among said plurality of pixels a first voltage for resetting the pixel to be occupied with the first molecular orientation state, a second voltage for resetting the pixel into a mixture state, including a minor proportion of the first molecular orientation state and a major proportion of the second molecular orientation state, and then a third voltage for causing a prescribed ratio of the first to second molecular orientation state at the pixel not smaller than the ratio in the mixture state.
