A highly orientated, liquid crystalline polymer having a light controlling function and suitable for use in the optoelectronic field is prepared by applying a solution of a polymer which exhibits a thermotropic liquid crystallinity onto a stretched polymer film, drying the applied solution, and thereafter heat-treating the thus-coated film at a temperature at which said liquid crystalline polymer exhibits a liquid crystal phase, for a time sufficient for the molecules of the liquid crystalline polymer to be orientated. |
