Abstract:
An active-matrix liquid crystal display device comprising:a plurality of display pixels, scanning lines, and signal lines disposed on a first transparent substrate;a liquid crystal orientation film disposed on said first transparent substrate either directly or through an insulating layer;a liquid crystal orientation film disposed on a second transparent substrate disposed in opposed relation to said first transparent substrate;a liquid crystal layer sandwiched between said first transparent substrate and said second transparent substrate;means for varying a polarized state of incident light applied to said first transparent substrate based on an oriented state of said liquid crystal layer;said display pixel comprising pixel electrodes, common electrodes, and an active element for applying an electric field to said liquid crystal layer substantially parallel to said first transparent substrate and said second transparent substrate; andsaid display pixel being connected to external control means for controlling the applied electric field freely according to a display pattern;wherein a distance between pairs of said pixel electrodes and said common electrodes, a width of said pixel electrodes, and a width of said common electrodes are constant; andsaid active-matrix liquid crystal display device further comprising means for varying an intensity of the applied electric field during application of the applied electric field to said display pixels, application of said electric field to said display pixels being controlled by said external control means according to said display pattern.
