Abstract:
An active-matrix liquid crystal display device, comprising:transparent substrates opposed to each other;a liquid crystal layer interposed between the opposed transparent substrates;pixel areas arranged on the surfaces of the transparent substrates on the liquid crystal side; anddisplay electrodes, reference electrodes, scan lines, video signal lines, reference signal lines and active devices arranged in the pixel areas;wherein 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 to modulate light passing through the liquid crystal layer;wherein 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 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;wherein the shield electrode is given the same potential as that of the reference electrodes; andwherein the shield electrode is formed in a multilayer structure comprising different layers of different materials with different reflectivities, and the material of the layer on the display surface side has a low reflectance.
