AKTIVMATRIX-FLÜSSIGKRISTALL-ANZEIGEVORRICHTUNGEN

In an active matrix liquid crystal display device of the kind having an array of pixel electrodes supported on an insulating film provided over active matrix circuitry, comprising switching devices, e.g. TFTs, and address lines, carried on a substrate with each pixel electrode being connected to the output of a respective switching device through the insulating film, and in which a row or column drive circuit is integrated on the substrate peripherally of the array, problems due to resistance in power or signal conductor lines of the drive circuit are conveniently overcome by extending the insulating film thereover and forming supplementary conductor tracks from the conductive layer constituting the pixel electrodes, each track being connected to its associated underlying conductor line through the film. Such tracks can be of greater width and thickness than the conductor lines.
