Abstract

Disclosed is a novel photo-responsive liquid crystal composition in which an oriented state of a liquid crystalline compound is capable of being controlled by an irradiation of light. The photo-responsive liquid crystal composition is composed of a liquid crystalline compound and a gelling agent mixed with the liquid crystalline compound to form a gelling mixture, wherein the liquid crystalline compound is capable of being controlled in a state orientated in one direction by the irradiation of light. In the photo-responsive liquid crystal composition, the liquid crystalline compound is oriented in a direction parallel to the direction of the irradiation of light. In the photo-responsive liquid crystal composition, the gelling agent is formed of a compound having an azobenzene structural part and a specific skeletal structure.
