ABSTRACT:
A liquid crystal display device includes a liquid crystal layer interposed between first and second substrates, a first electrode, and a second electrode having a plurality of linear portions. A reflective display portion and a transmissive display portion are included in one pixel. The thickness of the liquid crystal layer in the reflective display portion is smaller than that of the liquid crystal layer in the transmissive display portion. First and second polarizers having transmission axes approximately perpendicular to each other are provided on outer sides of the first and second substrates. The transmission axis of one of the first and second polarizers is set approximately in parallel to a liquid crystal orientation direction. The plurality of linear portions of the second electrode have predetermined electrode widths and a predetermined electrode distance therebetween.
