— An optimization method is proposed for achieving black and white representation in reflective STN‐LCDs with single polarizers which consist of an STN cell, a polarizer, and a reflector with two birefringent films between the STN cell and the reflector. In this method, the two films are optimized to achieve good black representation while an optimum voltage is applied to the STN cell. Good black and white representation with a maximum contrast ratio of 5:1, reflectance of 22%, and good achromaticity are achieved for an STN‐LCD fabricated using this method.
