Title: Reflective liquid crystal display device

Abstract: A reflective liquid crystal display device of the present invention has the following construction. A transparent electrode is provided via color filter layer on a transparent substrate positioned at the upper side of the device. A metallic reflective electrode is provided on a substrate positioned at the lower side of the device. An alignment layer is provided on the transparent electrode and on the metallic reflective electrode respectively. The transparent substrate positioned at the upper side and the substrate positioned at the lower side are arranged parallel to each other with alignment films provided on the transparent electrode and on the metallic reflective electrode facing each other. A liquid crystal layer is provided between the alignment films. A scattering film is provided on a surface of the transparent substrate positioned at the upper side opposite to the surface where the transparent electrode is provided. A polymer film and a polarization film are provided in that sequential order on the scattering film. The present reflective liquid crystal display device can express a black and white display in achromatic color having bright white display and with high contrast, and has low visual angle dependency and excellent optical characteristics.
