A ferro-electric liquid crystal electro-optical device, e.g., a display device or a shutter for a printer. The electro-optical device is driven in time-shearing. The device comprises a panel having a ferro-electric liquid crystal disposed between scanning electrodes and display electrodes, a drive portion for driving the panel and a control portion for controlling the drive portion. The panel can be driven by scanning only a part of the scanning electrodes for partially rewriting.
