Claim Text:
1. A reflective liquid crystal display device comprising: a first substrate provided with a reflective electrode; a second substrate provided with a transparent electrode, the transparent electrode oppositely disposed to the reflective electrode and provided for each of a plurality of pixels; a liquid crystal layer disposed between the first substrate and the second substrate; and an anisotropic scattering member provided on the second substrate, wherein: the anisotropic scattering member comprises a first surface and a second surface, the anisotropic scattering member includes a first refractive index region and a second refractive index region having a refractive index different from that of the first refractive index region, a refractive index difference between the first refractive index region and the second refractive index region at the first surface is larger than a refractive index difference between the first refractive index region and the second refractive index region at the second surface, the anisotropic scattering member is disposed so that light enters from the first surface and the light exits as scattered light from the second surface, and a phase difference is given to the light entered the anisotropic scattering member, and when a voltage is applied to a drive electrode and the transparent electrode, in the liquid crystal layer, a refractive index in an X-axis direction is lower than a refractive index in a Z-axis direction and a refractive index in a Y-axis direction is lower than the refractive index in the Z-axis direction, and in the anisotropic scattering member, a refractive index in the X-axis direction is higher than a refractive index in the Z-axis direction and a refractive index in the Y-axis direction is higher than the refractive index in the Z-axis direction, wherein: the X-axis direction is a direction along which pixels are arrayed, the Y-axis direction is a direction along which pixels are arrayed, and orthogonal to the X-axis direction, and the Z-axis direction is orthogonal to the X-axis direction and the Y-axis direction.
