A driving circuit and display device reducing waste of a bias current of an amplifier and conserving power. The driving circuit includes a driving signal supply mechanism (10), an amplifier mechanism (20A) and a control mechanism (60). The supply mechanism (10) supplies a driving signal having a target voltage represented during periodic update. The amplifier mechanism has an amplifier part (21,22), a current-adjustable constant current source (23a) and a switch part (30). The driving signal is input to the amplifier part (20A), which generates an output to a capacitance load according to the driving signal. The current source (23a) supplies and regulates a passing rate of the bias current to the amplifier part (21,22). The switch part (30) performs ON/OFF control to the current output to the current source. The control mechanism (60) detects a difference between the previous and present values of the target voltage to change a current value of the current source (23a).
