Abstract
A liquid crystal display which is a reflective liquid crystal display includes: a front substrate; a rear substrate; and a liquid crystal material layer disposed between the front substrate and the rear substrate, wherein an optical design is performed such that an extreme value of a liquid crystal applied voltage-reflectance curve in a state of being observed from a normal observing direction is shifted further to a lower voltage side than an extreme value of a liquid crystal applied voltage-reflectance curve in a state of being observed from a direction deviated from the normal observing direction, and wherein an anisotropic scatterer disposed such that a direction where scattering characteristics are the maximum is aligned with the normal observing direction is provided on the front substrate side.

A liquid crystal display which is a reflective liquid crystal display, comprising:
- a front substrate;
- a rear substrate;
- and
- a liquid crystal material layer disposed between the front substrate and the rear substrate,
- wherein an optical design is performed such that an extreme value of the liquid crystal applied voltage-reflectance curve varies depending on states of observing directions,
- wherein the optical design is performed such that the extreme value of the liquid crystal applied voltage-reflectance curve in a state observed from a normal observing direction is shifted further to a lower voltage side than an extreme value of a liquid crystal applied voltage-reflectance curve in a state observed from a direction deviated from the normal observing direction,
- wherein an anisotropic scatterer is disposed such that a direction where scattering characteristics are the maximum is aligned with the normal observing direction is provided on a front substrate side of the front substrate,
- wherein the anisotropic scatterer includes low refractive index regions and high refractive index regions,
- wherein high-low-index boundaries are disposed between the low refractive index regions and high refractive index regions, and
- wherein the anisotropic scatterer is disposed such that ambient light is scattered when light is incident from a direction substantially following the direction that the high-low-index boundaries extend, and such that the light is transmitted when light is incident from a direction substantially perpendicular to the direction that the high-low-index boundaries extends.
