Abstract
An active matrix type liquid crystal display system having a plurality of switching elements to which scanning signals and image signals are applied via scanning electrodes and signal electrodes on one of a pair of the substrates and a liquid crystal layer interposed between the pair of substrates, and an electrode structure for generating an electric field having a component substantially in parallel with one of the pair of the substrates. Scanning signals having at least two kinds of non-selective voltage values are applied to the scanning electrodes, whereby power consumption is reduced and image degradation of cross talk of the display system is prevented, in addition to obtaining extremely wide viewing-angle characteristics.
