Abstract
A liquid crystal display device comprises a reflective type liquid crystal panel with pixels which are arranged in two-dimentionally and which modulate irradiated light utilizing polymer dispersed liquid crystal capable of exhibiting two conditions including scattering and unscattering. The device is provided with an optical member having a multiple-interference effect at a predetermined angle with respect to the surface of the reflective type liquid crystal panel.
Claims13
A liquid crystal display apparatus, comprising:
- an illuminating light source which generates illuminating light;
- and
- a liquid crystal panel comprising an optical member which causes a multiple-interference effect, a transparent electrode, a liquid crystal layer for switching between a dark state and a light state corresponding to an applied voltage, and a reflective electrode along the optical path of said illuminating light in turn from said light source,
- wherein a surface of said optical member is inclined relative to a surface of said reflective electrode wherein the optical member is located on a light incident side of the liquid crystal panel causing the illuminating light to have a multiple-interference effect before being transmitted through said liquid crystal layer.
