<p>Disclosed is a polymerizable optically-active compound represented by the general formula (1). The polymerizable optically-active compound has a high helix-inducing ability and therefore, when added to a liquid crystal composition, can achieve a desired helical pitch length of the liquid crystal composition without largely deteriorating the physical properties or optical properties of the liquid crystal composition. A liquid crystalline material, particularly a liquid crystalline material having a cholesteric phase, containing the polymerizable optically-active compound can be used suitably as a material for the production of an optically anisotropic material excellent in heat resistance, solvent resistance, transparency, optical properties and liquid crystal orientation fixation ability, and can also be used as a liquid crystal orientation film, a liquid crystal orientation-controlling agent, a coating material, a material for the production of a protective board and the like. (1) wherein X1 and X2 independently represent a (meth)acryloyloxy group: and Y1 and Y2 independently represent a single bond, an alkylene group which may have a branch having 1 to 8 carbon atoms, an ether bond, a thioether bond,-COO-,-OCO-,-OCO-O-,-S-CO-,-CO-S-, a 6-membered ring which may have a substituent, a naphthalene ring which may have a substituent, or a combination thereof.</p> |
