Optical element |
| abstract |
Provided is an optical element with which a high diffraction efficiency can be obtained with a simple configuration. The optical element includes: an optically-anisotropic layer that is formed using a composition including a liquid crystal compound, in which the optically-anisotropic layer has a liquid crystal alignment pattern in which a direction of an optical axis derived from the liquid crystal compound changes while continuously rotating in at least one in-plane direction, and the optically-anisotropic layer has a region in which an alignment direction of a liquid crystal compound in at least one of upper and lower interfaces has a pre-tilt angle with respect to the interface. |
