Abstract:
1. A display comprising a bend aligned nematic liquid crystal cell, a pair of polarizers, one disposed on each side of the bend aligned nematic liquid crystal cell, the polarizers having transmission axes orthogonally crossed with respect to each other, and a compensation film disposed between the bend aligned nematic liquid-crystal cell and each polarizer, said film containing a positively birefringent material oriented with its optic axis tilted in a plane perpendicular to the liquid crystal cell surface plane, wherein the compensation films comprise a first positively birefringent material disposed on a base film and a second positively birefringent material disposed on the said first positively birefringent material, wherein the first and second positively birefringent materials each have their optical axes in planes that are perpendicular to the liquid crystal cell and the planes are perpendicular to each other.
