    Abstract: A laminate is capable of forming an orientation film formed by orienting a rod-like liquid crystal compound or a disk-like liquid crystal compound having a horizontal orientation ability or a vertical orientation ability with respect to a surface of the laminate, on the surface, by using an orientation restraining force of the surface, the laminate including: a cholesteric liquid crystal layer. An optical film sequentially includes: a support; a cholesteric liquid crystal layer; and an orientation film.
