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.
