Optical compensator with solvent and process

摘要

Disclosed is an optical compensator film for a liquid crystal display and a process for forming the film comprising the steps of (1) coating an anisotropic layer containing liquid crystal prepolymer materials and an organic solvent system that is both miscible with said materials and has a weight average boiling point of from 85 to 130° C. and subsequently (2) drying the layer. The compensator widens the viewing angle characteristics of liquid crystal displays and is readily manufactured with improved quality and uniformity of coated layers.
