Abstract:
A liquid crystal display comprising:(a) a first sheet polarizer having a first absorbing axis; (b) a second sheet polarizer having a second absorbing axis; (c) a liquid crystal layer disposed between said first and second sheet polarizers and having a first major surface defining a plane, and a second major surface; (d) a first electrode proximate to said first major surface of said liquid crystal layer; and (e) a second electrode proximate to said second major surface of said liquid crystal layer, wherein said first sheet polarizer comprises a plurality of elongate light absorbers having a long axis sandwiched between an optically transparent superstrate having a plurality of parallel first grooves on an inner surface thereof, said inner surface of said superstrate defining a contour, and a substrate having an inner surface with a plurality of parallel second grooves thereon that are complementary to said plurality of first grooves and wherein said long axis of said elongate light absorbers conforms to said contour.
