Title: Active matrix liquid crystal display device

Abstract: An active matrix liquid crystal display device includes first and second substrates, a liquid crystal layer disposed between the first and second substrates, and plural image signal lines and scan signal lines formed on the first substrate. Respective pixel regions are formed by adjacent image signal lines and adjacent scan signal lines and have at least an active device, with a first electrode and a second electrode being provided in each pixel region. The first electrode is connected to the active device of one pixel region, and the second electrode of one pixel region is connected to the second electrode of an other pixel region which adjoins the one pixel region in the extended direction of the image signal line. The second electrode is connected for at least three adjacent pixel regions in the extended direction of the image signal line.
