Abstract

Reflective liquid crystal display (LCD) with guest-host (GH)mode and quarter-wave plate was proposed by Coles. We have modefied this mode by fabricating the wave plate inside the cell to obtain high resolution and taking homeotropic alignment to obtain high brightness. This LCD has gray scale capability, high reflectance of more than 60% with contrast of 5 and low drive voltage of 10V.
