Liquid crystal composition, liquid crystal device and display apparatus

A liquid crystal device with a decreased temperature-dependence of response speed is obtained by using a liquid crystal composition having a temperature range of smectic A phase, wherein the composition forms a plurality of first molecular layers each composed of plural liquid crystal molecules in smectic A phase, and also a temperature range of chiral smectic C phase, wherein the composition forms a plurality of second molecular layers each composed of plural liquid crystal molecules in chiral smectic C phase, the second molecular layers being formed through deformation from the first molecular layers and showing a degree of deformation with respect to the first molecular layers which varies at different temperatures. The temperature range of chiral smectic C phase includes a) a first temperature range where the second molecular layers show a degree of deformation which increases on temperature decrease down to a mediate temperature, and b) a second temperature range, below the first temperature range, where the second molecular layers show a degree of deformation which decreases on further temperature decrease below the mediate temperature.
