Liquid crystal composition, liquid crystal device and liquid crystal apparatus using same
 A liquid crystal device with little temperature-dependence of drive characteristics, such as response speed, and with good storage stability, can be produced by using a liquid crystal composition, successively assuming SmA (smectic A) phase and SmC* (chiral smectic) phase on temperature decrease. The layer spacing composition has a temperature-dependence of layer spacing d in smectic phase such that the layer spacing d increases, is constant or decreases on temperature decrease in SmA phase temperature range, assumes a first transition point where the layer spacing d abruptly decreases on temperature decrease in vicinity of transition temperature from SmA phase to SmC* phase, and assumes a second transition point where the layer spacing d commences to increase on further temperature decrease below the first transition point in SmC* temperature range.
