ABSTRACT:
An active matrix liquid crystal display device includes a pair of substrates and a liquid crystal layer, a video signal lines and scan signal lines delimiting pixel areas having pixel electrodes and display electrodes, reference electrodes and active devices. The display electrodes are arranged on one of the substrates, and the reference electrodes are arranged on another of the substrates. A part of the reference electrodes have a first layer formed in the substrate side and a second layer formed in the liquid crystal layer side. Each of the display electrodes and the reference electrodes has a slit, the slit of the display electrodes and the slit of the reference electrodes being shifted with respect to one another in plan view.
