ABSTRACT:
An LCD (Liquid Crystal Display) of the present invention includes a pair of substrates facing each other and at least one of which is transparent. A liquid crystal composition intervenes between the substrates. Scanning wirings and signal wirings are arranged on one substrate in a matrix configuration. Pixel electrodes each constitutes one pixel. Switching devices each is positioned at a portion where one of the scanning wirings and one of the signal wirings intersect each other, for controlling the application of a voltage to the associated pixel electrode. Common electrodes are formed on the other substrate. The liquid crystal composition has positive dielectric constant anisotropy and is oriented vertically to the facing surfaces of the substrates when a voltage is not applied. The common electrodes are parallel to the pixel electrodes and positioned at both sides of said pixel electrodes.
