Abstract:
The present invention provides a liquid crystal composition having at least a liquid crystal and a chiral dopant, in which the chiral dopant is a compound having a liquid crystalline group of a specific structure bonded to a rigid optically active compound. The present invention provides a liquid crystal element having at least a pair of electrodes in which at least one of the electrodes is a transparent electrode, and a liquid crystal layer containing the liquid crystal composition. The present invention also provides a reflective display material and a light-controlling material having at least the liquid crystal element, and a method of preparing the liquid crystal element by adding the chiral dopant to a host liquid crystal.
