Liquid crystal composition, optical element, and light guide element |
| abstract |
The present invention addresses the problem of providing: a liquid crystal composition that is capable of yielding an optical element having exceptional diffraction efficiency, as relates to an optical element that has an optically anisotropic layer having a liquid crystal alignment pattern in which the orientation of an optical axis derived from a liquid crystal compound changes while continuously rotating along at least one direction within a plane; an optical element; and a light guide element. The liquid crystal composition according to the present invention contains a rod-shaped liquid crystal compound and a disc-shaped liquid crystal compound, and the ratio of the twist elastic constant K22 and the spray elastic constant K11 of the liquid crystal composition satisfies 0.7≤K22/K11. |
