Abstract:
1. A liquid crystal display device comprising: a viewing side substrate; another substrate opposing the viewing side substrate; a liquid crystal layer interposed between the viewing side substrate and the other substrate, the liquid crystal layer being composed of liquid crystal having a negative dielectric anisotropy; an other substrate circularly polarizing member provided outside the other substrate, the other substrate circularly polarizing member enabling substantially circularly polarized light to be incident on the liquid crystal layer; and a viewing side circularly polarizing member provided outside the viewing side substrate, the viewing side circularly polarizing member enabling substantially circularly polarized light to be incident on the liquid crystal layer, the viewing side circularly polarizing member including: the liquid crystal, the linearly polarizing plate, and the first and second retardation plates satisfying the following relationships: 1) in the case that 0.8×Δn·d−160<2×Rc<0.8×Δn·d−20, then 2) in the case that 2×Rc<0.8×Δn·d−160, then 3) in the case that 0.8×Δn·d−20<2×Rc, then wherein Rc is the phase difference of the second retardation plate, Δn is the refractive index anisotropy of the liquid crystal, d is the thickness of the liquid crystal layer, θ θ
