Liquid crystal composition, liquid crystal display device and liquid crystal displaying method

摘要

Disclosed is a liquid crystal composition by which the state of molecular orientation of a liquid crystalline compound can be stably maintained even when no electric field is caused to effect on, and moreover the state of molecular orientation of the liquid crystalline compound can be changed, and a liquid crystal display device and a liquid crystal displaying method by which a displayed state can be stably retained even after the action of an electric field is ceased, and moreover the displayed state can be dissolved with ease. The liquid crystal composition contains a liquid crystalline compound and a liquid crystal orientation state-regulating agent for regulating the orientated state of the liquid crystalline compound by gelling, wherein a phase transition temperature between an isotropic liquid phase and a liquid crystal phase in the liquid crystalline compound is higher than a gelling temperature by the liquid crystal orientation state-regulating agent. The liquid crystal display device has a liquid crystal layer formed of the liquid crystal composition.
