Abstract: Disclosed is an optical compensator and process for liquid crystal displays comprising a transparent polymeric support, an orientation layer, and an optically anisotropic layer, in order, wherein the anisotropic layer contains a surfactant. The uniformity and quality of this film is enhanced by the use of a surfactant in the optical anisotropic layer.

Abstract: A process for making an optical compensator comprising the steps of coating a photo-alignable resin in a solvent onto a substrate; drying the resin-containing coating to form a orientable layer; heat treating the orientable layer before and/or after orientation, orienting the orientable layer in a predetermined direction; coating an anisotropic liquid crystal compound in a solvent carrier onto the orientation layer; drying the anisotropic layer. In a preferred embodiment, these steps are repeated so that the optical axis of a first anisotropic layer is positioned orthogonally relative to the respective optical axis of a second anisotropic layer about an axis perpendicular to the plane of the substrate.
