PURPOSE: To provide a driving circuit and a driving method capable of lowering the power consumption of an optoelectronic device with simple circuit constitution. CONSTITUTION: The liquid crystal display panel is driven with scanning line inversion drive. Then, a virtual scan period is provided between the Mth scan period and the first scan period of the next frame and, in the virtual scan period, a counter electrode VCOM is set to be at a voltage level different from that of the VCOM in the Mth and the first scan periods and the display panel is driven. In a period T1 when the counter electrode VCOM becomes to be at VC1, the data line is driven with a P type operational amplifier OP1 having a P type driving transistor and, in a period T2 when the VCOM becomes to be at VC2, the data line is driven with an N type operational amplifier OP2 having an N type driving transistor. The voltage level of the data line is preliminarily changed to a power source VDD or a power source VSS before the drive by setting the data to be in a high impedance state at the time for the switchover of the period T1 and the period T2 and by utilizing positively the parasitic capacitance between the counter electrode and the data line.
