Abstract
A reflective liquid crystal display device combined with an optical system with a wire grid is provided for light modulation by a liquid crystal layer. This layer, made of nematic liquid crystal having negative dielectric anisotropy, is formed such that first and second orientation directions on first and second substrates are rotated by '60±α' and '60±β' degrees in first and second rotating directions starting from a reference direction, respectively. The first and second rotating directions are mutually opposite, the reference direction is parallel to the first and second substrates and within in an angular range defined by a central angle plus ±5 degrees wherein the central angle is ±45 degrees from an oscillation direction of incident polarized light, and a relationship of |α|+|β|≦10 (α and β are zero or positive integers) is fulfilled.
