Abstract: Before a potential of counter electrode is changed, a potential holding circuit fixedly holds potentials of data signal lines S during a non-selective period of scanning signal lines G. This prevents the potentials of the data signal lines S from being an undesirably large potential, which is caused by coupling capacitors between the counter electrode and each data signal line S, whereby it is possible to supply to the pixel capacitor an electric charge corresponding to a gradation to be displayed, by using the relatively low potentials of the data signal lines S. This lowers a power supply voltage of a data signal driving circuit SD, thus reducing the electric power consumption. In short, with this arrangement, a liquid crystal display device can perform an opposed AC drive for line-inversion drive, frame-inversion drive and the like, by low power supply voltage of the data signal line driving circuit SD, thereby reducing the electric power consumption.

Abstract: In a PDP driver, first and second signal lines for a voltage of Vs and third and fourth signal lines for a voltage of 0V are formed. While maintaining Y and X electrodes of the panel capacitor at Vs and 0V, a first current path is formed from the first signal line to the fourth signal line through an inductor to supply a first-directional current to the inductor. A second current path is formed from the Y electrode to the X electrode through the inductor to change the Y and X electrode voltages using the resonance. When the electrode voltages become 0V and Vs, a third current path is formed from the third signal line to the second signal line through the inductor to reduce the first-directional current.
