  • Patent number: 6278508
    Abstract: A reflector electrode is provided with hills and valleys thereon, and the reflector electrode is formed on an inside face of a transparent substrate having a transparent electrode and an opposite substrate. Light-scattering-liquid-crystal is provided with forward-scattering component and back-scattering component, so that scattering of reflected light from the reflector electrode is increased when the light-scattering-liquid-crystal is transparent. As a result, contrast is less dependent on a viewing angle, and a brighter quality display with higher color purity can be obtained.
