Abstract
A liquid crystal display device in which low power consumption and bright white color display are enabled to achieve high contrast as well as a response speed and picture quality compatible with a moving picture. A transparent substrate having a transparent electrode and a polarizing plate and a facing side substrate having plural pixel electrodes formed of a light reflective material and plural switching elements driving these pixel electrodes are arranged at a predetermined separation so that the transparent electrode and the pixel electrodes face each other. A liquid crystal layer formed of a nematic liquid crystal is interposed between the transparent substrate and the facing side substrate. The nematic liquid crystal is preferably a negative type nematic liquid crystal having negative anisotropy. The surfaces of the plural pixel electrodes towards the liquid crystal layer preferably present surface irregularities. If the surfaces of the pixel electrodes towards the liquid crystal are not irregular surfaces, the transparent substrate preferably has a light-scattering layer. A color filter is preferably provided on the transparent substrate or on the facing side substrate.
