Abstract
A liquid crystal display comprises a top polarizeran optical compensating element, an anisotropic scattering layera scattering layerand a liquid crystal deviceincorporating therein a reflective layerWhen the direction of viewing direction of the anisotropic scattering layer is designated as the Y-axis direction, and a direction oriented substantially at right angles to the Y-axis direction is designated as the X-axis direction, light entering the anisotropic scattering layer is scattered over a wider angle along the Y-axis direction than along the X-axis direction. Further, the incident angle dependence of the straight-go transmittance of the anisotropic scattering layer is symmetrical about the layer normal, and the straight-go transmittance in the layer normal direction is lower than the straight-go transmittance in any oblique direction.
