Abstract:
An active matrix liquid-crystal display device comprising:a substrate; a plurality of switching elements and a plurality of pixel electrodes formed in a matrix arrangement on said substrate; scanning lines controlling said switching elements; signal lines supplying data signal to said switching elements; terminals making electrical connections between said scanning and signal lines and external driving elements, and comprising a metal layer which forms said scanning line or said signal line, an interlayer film formed on said metal layer, and a transparent electrode forming said pixel electrode; contact holes formed in said interlayer film, through which said metal layer and said transparent electrode are connected to each other via a transparent electrode formed in said contact hole; and an anisotropic conductive film connecting said active matrix substrate to said external driving elements, wherein said active matrix liquid-crystal display device comprises a dummy contact hole provided through said interlayer film and said dummy contact hole disposed between adjacent terminals.
