The smectic liquid crystal is disposed to form a first region wherein the smectic liquid crystal layers are aligned to have a layer inclination angle smaller than a calculated layer inclination angle based on a temperature-dependent layer spacing-changing characteristic or are aligned in a direction perpendicular to the substrates to form a bookshelf structure, and a second region wherein the smectic liquid crystal layers are aligned to form a chevron structure having a substantial layer inclination angle or having a layer inclination angle substantially equal to a calculated layer inclination angle based on a temperature-dependent layer spacing-changing characteristic. The liquid crystal device having the first an second regions described above is effective in improving a contrast ratio and a driven margin parameter.

摘要： 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).
