Abstract

We propose a new optical configuration of a hybrid-aligned nematic liquid crystal cell for reflective displays, which consist of a biaxial film for obtaining wide viewing angle and a half-wave film for achieving high contrast. As a result, we can achieve wide viewing angle of (80( for the horizontal direction and (50( for the vertical direction and uniform reflection spectrum.
