Liquid crystal display device having comblike bent interdigital electrodes

Abstract

An active matrix type liquid crystal display device of the transverse electric field system, wherein display pixels are constituted on a substrate by scanning signal lines, video signal lines, pixel electrodes and active elements in order to obtain an image having good visual field angle characteristics and a high display quality with less residual image. A liquid crystal alignment film is formed directly or via an insulating layer on the substrate. The substrate is opposed to another substrate having a color filter forming a liquid crystal alignment film, and the liquid crystal layer is held by the two substrates. The electrodes and the active elements are so constituted that an electric field can be applied to the liquid crystal layer substantially in parallel with the substrate. The electrodes and the active elements are connected to an external control means capable of arbitrarily controlling the applied electric field depending upon a display pattern. The liquid crystal display device is further provided with a polarizer means capable of changing the optical characteristics depending upon the state of alignment of the liquid crystal layer. The video signal lines and the pixel electrodes are bent within a range of 1 to 30 degrees relative to the direction of liquid crystal alignment.
