Abstract:
1. A liquid crystal display device comprising a structure in which a first substrate including a reflective layer, a liquid crystal layer, a second substrate, and a polarizer are stacked in this order from a back face to a display face, wherein the liquid crystal display device includes a retardation layer, in a region on a liquid crystal layer side of the reflective layer of the first substrate, or in a region where the reflective layer is not arranged of the first substrate, or in the second substrate, and the retardation layer provides two or more regions having different retardations in a display surface plane; wherein the liquid crystal display device includes a reflective region where the reflective layer is arranged and a transmissive region where the reflective layer is not arranged, and the retardation layer provides retardations different between the reflective region and the transmissive region; wherein, in the reflective region, the retardation layer produces a retardation of substantially λ/4 between polarization components of light, the light having a wavelength of λ and entering from a direction substantially vertical to the retardation layer; wherein the first substrate or the second substrate includes two or more color layers having different dominant wavelengths in the region on the liquid crystal layer side of the reflective layer, the retardation layer produces a retardation of substantially λ
