Abstract:
A liquid crystal display device of an embodiment of the present invention includes a liquid crystal layer, a specular reflection layer, the polarization layer disposed on the viewer's side, a retardation layer interposed between the liquid crystal layer and the polarization layer, and a light scattering layer disposed on the viewer's side of the polarization layer. The light scattering layer has a scattering surface. The scattering surface includes a macro uneven structure which has light scatterability and a micro uneven structure which is superimposedly formed over the macro uneven structure and which is smaller than visible light wavelengths.
