Patent ID: 7671945

Claim:
A liquid crystal display assembly comprising: a polarizer adjacent to a lighting source, said polarizer having an oriented absorption axis; a viewer side analyzer having an absorption axis substantially perpendicular to the oriented absorption axis of the polarizer adjacent to the lighting source; a liquid crystal cell comprising a twisted nematic liquid crystal material between the polarizer and the analyzer; and at least one compensator assembly located between the polarizer and the analyzer, the at least one compensator comprising: an aromatic polyimide-based UV curable acrylate film with a first surface rubbed to create an alignment layer; and a polymeric nematic liquid crystal film on the alignment surface of the rubbed aromatic polyimide-based UV curable acrylate film, said rubbed aromatic polyimide-based UV curable acrylate layer causing a pretilt in the polymerized nematic liquid crystal film.
