Abstract: A polymeric liquid crystal composition comprises a polymer mesomorphic compound having an asymmetric carbon atom and a low-molecular weight mesomorphic compound. The composition can be easily formed into a film of a large area, shows a response speed which is not substantially different from that of the low-molecular weight mesomorphic compound alone and stably retains alignment resistant to pressure or heat impact. Such a good alignment is especially obtained when the polymeric liquid crystal composition is incorporated in a liquid crystal device by being disposed between a pair of substrates preferably having an alignment face provided with an orientation characteristic for aligning the molecular axis of the liquid crystal composition in one direction. It is suitable that the polymer mesomorphic compound is optically active and has a helical rotation direction opposite to that of the low-molecular weight mesomorphic compound.
