Abstract
An optical element comprises a molded body of a composition of a cross-linked macromolecular liquid crystal and a resin. An optical element composed of a macromolecular liquid crystal composition where the granules of the cross-linked macromolecular liquid crystal are dispersed into the resin as a binder is preferable. The element can be made by preparing in advance granules of the cross-linked macromolecular crystal liquid by a physical or chemical crushing manner, dispersing the granules in the binder, and then molding it.
