Abstract
A liquid crystal device suitable for analog gradational display according to active matrix drive is formed using a chiral smectic liquid crystal. The voltage-transmittance (V-T) characteristic change accompanying a cell thickness change can be minimized to allow the production of such a liquid crystal device at a higher yield. In the liquid crystal device, the liquid crystal is placed in such an alignment state that the liquid crystal is monostabilized under no voltage application and is tilted in response to the application of voltages of opposing polarities so that the saturation voltage becomes larger at small cell thickness (liquid crystal layer thickness).
