For an electronic holographic display with wide viewing-zone angle, we propose a lateral electric field drive system based on continuous potential-difference driving by lateral transparent electrodes. Light modulation was evaluated to confirm the independent driving of each pixel with high resolution of 1µm pitch. We also showed that by combination of driving and grounding electrodes, 2-dimensional driving is possible.
