Patent ID: 7515231

Claim:
A liquid crystal display assembly comprising, a) a polarizer adjacent a lighting source, said polarizer having an oriented absorption axis, b) a viewer side analyzer having an absorption axis substantially perpendicular to the oriented absorption axis of the polarizer adjacent the lighting source, c) a liquid crystal cell comprising a twisted nematic liquid crystal material between the polarizer and the analyzer, and d) at least one compensator assembly located between the polarizer and the analyzer, the compensator comprising, i) a crosslinked polyvinyl alcohol film with a first surface rubbed to create an alignment layer, and ii) a polymeric nematic liquid crystal film on the alignment layer of the rubbed crosslinked polyvinyl alcohol film, said rubbed crosslinked polyvinyl alcohol layer causing a pretilt in the polymerized nematic liquid crystal film wherein the compensator assembly includes a triacetyl cellulose substrate, a second surface of the polyvinyl alcohol film being in contact with said triacetyl cellulose substrate the triacetyl cellulose substrate having substantially no in-plane retardance and a negative out-of-plane retardance from about 30 nm to about 120 nm.
