摘要

PROBLEM TO BE SOLVED: To correct crosstalk induced between scanning electrodes and signal electrodes in a TFD (Thin Film Diode) liquid crystal display element. SOLUTION: There is provided a dummy scanning electrode 50 that intersects with a plurality of signal electrodes 14 and 14 and is arranged in the same manner as a plurality of scanning electrodes 12 and 12. Since the dummy scanning electrode 50 is connected to the inverting input terminal of an operational amplifier 32, the voltage of the dummy scanning electrode 50 is maintained at a reference voltage "VGND." When the crosstalk from the plurality of signal electrodes 14 and 14 occurs, a current "Ix" flows through a resistor 34 so as to maintain the voltage at the dummy scanning electrode 50 at the reference voltage "VGND." The voltage to be applied to the plurality of scanning electrodes 12 and 12 is increased or decreased in accordance with the current "Ix" in order to correct the crosstalk. COPYRIGHT: (C)2004,JPO
