Abstract
A inverting amplifier circuit for controlling the voltage of the signal line S is provided in a load drive circuit . Before the inverting amplifier circuit controls the voltage of the signal line S, the voltage of each inverter INV to INV constituting the inverting amplifier circuit is set at the voltage substantially equal to each threshold voltage thereof. As a result, even when the threshold voltages of the inverters INV to INV vary, it is possible that this would not exert any influence on the voltage of the signal line S. Therefore, it is possible to provide the load drive circuit not to be affected by the variation of the characteristic of the inverting amplifier circuit
