PROBLEM TO BE SOLVED: To provide a display device in which display picture quality is improved and power consumption is reduced. SOLUTION: The display device is equipped with an oscillating circuit 1 to generate a reference clock CLK (osc), a counter circuit 2 for display to generate a frame sync signal CLK (frm). a line select reference clock signal CLK (drv), and a voltage multiplying motion reference clock obtained by multiplying the line select reference clock signal CLK (drv) from the reference clock, a divided frequency circuit 4 to input the frame sync signal CLK (frm) as a reset signal and to output a voltage multiplying motion clock CLK (dcdc) by frequency dividing the voltage multiplying motion reference clock, a voltage multiplying circuit 5 to fulfill a charge period and a discharge period in accordance with the voltage multiplying motion clock CLK (dcdc), and a driver circuit 3 to receive a multiplying voltage from the voltage multiplying circuit and to drive a scanning line in accordance with the line select reference clock signal CLK (drv).
