ABSTRACT:
A driver circuit to drive a display by inverting the voltage polarity operates with a reduced power consumption. The driver circuit includes a driving voltage selector circuit including positive and negative driving voltage selector circuits alternately arranged therein and a circuit which conducts a change-over operation between a state in which signals respectively from the positive and negative driving voltage selector circuits are respectively outputted to first and second terminals in a first horizontal period and a state in which signals respectively from the positive and negative driving voltage selector circuits are respectively sent to second and first terminals in a second horizontal period.
