摘要：
A voltage control circuit which can prevent the occurrence of imprint phenomenon is provided.In a voltage control circuit which applies voltage to a pair of electrodes including a first and a second electrode, a control unit switches the voltage applied to the pair of electrodes, in response to an operation mode of this circuit.In a normal mode, the control unit fixedly applies a first voltage to the first electrode and applies a data voltage of the first voltage or the second voltage to the second electrode, based on an instruction from the control unit.In an inversion mode, the second voltage is fixedly applied to the first electrode, and the data voltage of the first voltage or second voltage is applied to the second electrode. The control unit switches the mode between the normal mode and the inversion mode, in a predetermined cycle.
