Abstract
In a matrix type of liquid crystal display panel, in which an individual switching element is provided on the panel for each of the display elements, the electrodes of each display element comprise a first comb-shaped electrode pattern, to which a display signal voltage is applied through a switching element, and a second comb-shaped electrode pattern which is held at a reference potential, with the first and second comb-shaped patterns being mutually intermeshed and formed upon a single substrate of the panel, whereby application of a display signal voltage causes an electric field to be produced in a direction substantially parallel to the substrate plane to thereby act upon the liquid crystal, rather than in a direction normal to the substrate plane as in the case of a conventional type of liquid crystal display panel.
Claims8
In a liquid crystal display panel having a layer of liquid crystal material enclosed between a pair of substrates, a set of row electrodes and a set of column electrodes formed on said substrates to mutually intersect, a plurality of display electrodes arranged in positions corresponding to intersections of said row and column electrodes, a plurality of switching elements each coupled between an intersection of said row and column electrodes and a corresponding one of said display electrodes, a source of scanning signals for selectively rendering said switching elements conductive and a source of display signal voltages, said display signal voltages being selectively applied to said display electrodes through said switching elements in response to said scanning signals, and a reference electrode which is held at a predetermined potential, the improvement whereby said display electrodes are arranged in relationship to said reference electrode such that an electric field is applied to said liquid crystal material in a direction having at least a component directed parallel to the plane of said substrates in response to a potential difference between said display signal voltage applied to one of said display electrodes and the potential of said reference electrode.
