Abstract:
An active matrix type liquid crystal display system comprising:a first substrate having on one surface a plurality of scanning electrodes, a plurality of signal electrodes formed to intersect with said plurality of scanning electrodes, a switching element formed in each of the intersecting portions of said plurality of scanning electrodes and said plurality of signal electrodes, a pixel electrode connected to said switching element, a counter electrode formed so as to face said pixel electrode;a second substrate placed so as to face said first substrate;a liquid crystal component interposed in a gap between said first substrate and said second substrate;a signal driver supplying an image signal to each of said plurality of signal electrodes; anda scanning driver applying a scanning signal to each of said plurality of scanning electrodes to produce a display;wherein a first voltage is applied between said pixel electrode and said counter electrode to generate an electric field to said liquid crystal component which is predominantly in parallel to said first and second substrates, a second voltage obtained by adding a third voltage of different polarity to a base voltage is applied to said counter electrode, and a fourth voltage is applied to at least one of said plurality of scanning electrodes so as to maintain a difference between a voltage of said scanning electrode and said second voltage applied to said counter electrode neighboring said scanning electrode.
