ABSTRACT:
An optical modulation device comprises scanning electrodes and signal electrodes disposed intersecting with each other to form a pixel at each intersection of the scanning electrodes and signal electrodes. The contrast of each pixel is discriminated depending on an electric field applied thereto. The optical modulation device is driven by a method comprising providing the scanning electrodes with at least three potential levels of V.sub.1, V.sub.2 and V.sub.3 which satisfy the relation of V.sub.1 >V.sub.2 >V.sub.3 and providing the signal electrodes with at least three levels of V.sub.4, V.sub.5 and V.sub.6 which satisfy the relation of V.sub.4 >V.sub.5 >V.sub.6 ; wherein the potentials V.sub.1, V.sub.3, V.sub.4 and V.sub.6 are set to satisfy the relation of V.sub.1 -V.sub.3 =V.sub.4 -V.sub.6.
