PROBLEM TO BE SOLVED: To provide a liquid crystal material different from the conventional one and changing the molecular orientation by responding to an external field, concretely, changing the shape of the liquid crystal molecule between a rod shape and a disc shape by the change of the external field by temperature change, light irradiation or the like, and according to the change, causing the phase transition between liquid crystal phases. SOLUTION: The liquid crystalline compound obtained by arranging two or more rod-shaped mesogenic groups around a flat molecule changes the whole shape of the liquid crystalline compound between the rod shape and the disc shape according to the change of the external field, and accordingly changes the molecular orientation style (liquid crystal phase) of the liquid crystalline compound (phase transition).
