Abstract
An active-matrix type liquid crystal display device having transparent substrates, a liquid crystal layer, pixel areas arranged on the surfaces of the transparent substrates on the liquid crystal side, and display electrodes, reference electrodes, scan lines, video signal lines, reference signal lines and active devices arranged in the pixel areas. A voltage is applied between the display electrodes and the reference electrodes to produce an electric field parallel to the transparent substrates in the liquid crystal layer, and on one of the transparent substrates the reference electrodes are arranged on both sides of the video signal lines, and on the other transparent substrate a shield electrode which is an electrically connected conductive member is formed to cover, as seen in plan view, the video signal lines in the pixel areas and a part of the reference electrodes on both sides of the video signal lines.
