Abstract
Ambient light incident upon a polarizerpasses through a liquid crystal layerand is then reflected by reflective filmsvia transparent electrodesThe reflected light passes again through the liquid crystal layerand the polarizerand is output to the outside thereby displaying an image in a reflective displaying mode. The reflective filmsare disposed at locations corresponding to the respective transparent electrodessuch that they are spaced from each other. In this structure, some ambient light passes through the spaces between adjacent transparent electrodes, however, such light is not reflected by the reflective filmstoward the outside and thus a reduction in contrast due to such reflection is prevented.
