Optical element, light-guiding element, and liquid crystal composition |
| abstract |
The present invention addresses the problem of providing: an optical element having exceptional diffraction efficiency, the optical element having an optically anisotropic layer that has a liquid crystal orientation pattern in which the orientation of an optical axis derived from a liquid crystal compound changes while being successively rotated along at least one direction in a plane; a light-guiding element; and a liquid crystal composition. The optical element has an optically anisotropic layer formed using a liquid crystal composition that contains a liquid crystal compound having polymerizable groups. The ratio of the bend elasticity constant K33 of the liquid crystal composition and the splay elasticity constant K11 thereof satisfies the expression 0.8≤K33/K11≤1.2 at any temperature in the nematic temperature region. The optically anisotropic layer has a liquid crystal orientation pattern in which the orientation of an optical axis derived from the liquid crystal compound changes while being successively rotated along at least one direction in a plane. |
