    摘要: The present invention relates to a method for producing a viewing angle compensator for liquid crystal displays which diminishes the view angle dependency of the liquid crystal display. More specifically, the method of making the view angle compensator involves applying a coating of an optically active polyester containing as a constituent a hydrocarbon unit selected from the group consisting of bulky aromatic units, polycyclic hydrocarbon units and ortho-substituted aromatic units, or a composition containing a liquid crystalline polyester which contains the said hydrocarbon unit as a constituent and also contains an optically active compound to a light transmitting substrate. The foregoing coating is heat-treated at a temperature higher than the glass transition point of the polyester to form a cholesteric orientation. The heat-treated coating is thereafter cooled to a temperature lower than the glass transition temperature to solidify a cholesteric structure.
