Abstract
Display device in which the viewing angle dependence is compensated by providing sub-cells having a mutually different viewing angle dependence via a replica method in which the liquid crystal orienting layer is given a sawtooth pattern. Orienting is realized by rubbing or by providing a Langmuir-Blodgett film. Due to variation of the angles of the sawtooth structure, different tilt angles with respect to the substrate are obtained in different areas.
