ABSTRACT:
A process for making an optical compensator, comprising the steps of coating a orientable resin in a solvent onto a support; drying the resin-containing coating; orienting the resin-containing layer in a predetermined direction; coating a nematic liquid-crystal compound in a solvent carrier onto the orientation layer; drying the nematic liquid-crystal-containing coating; thermally treating the nematic liquid-crystal compound layer, cooling the nematic liquid-crystal compound layer, polymerizing or curing the anisotropic nematic liquid-crystalline layer to form an integral component; and optionally repeating the above steps on top of the integral component so that the optical axis of the first anisotropic nematic liquid-crystal layer is positioned orthogonally relative to the respective optical axis of the second anisotropic nematic liquid-crystal layer about an axis perpendicular to the plane of the support.
