发明名称 Transverse electric field system liquid crystal display device suitable for improving aperture ratio
摘要 An active matrix type liquid crystal display device capable of accomplishing an angle of visual field equal to that of a CRT and controlling the display by an electric field substantially parallel to a substrate surface provides bright display and requires lower power consumption. Pixel electrodes and opposed electrode capable of applying an electric field substantially parallel to a substrate surface is constituted, the pixel electrodes or the opposed electrodes are constituted by transparent electrodes, and the orientation state of a liquid crystal and the axis of polarization of a polarizer are constituted so that dark display is effected at the time when no field is applied. In this way, there can be provided a transverse field system active matrix type liquid crystal display device having a wide visual field angle characteristics, excellent contrast ratio and aperture ratio and capable of improving maximum transmissivity.
