A display device includes a display panel having scan lines, and a booster circuit configured to generate an output voltage and to supply the output voltage as power source to the display panel. The booster circuit includes a charge pump and a feedback circuit section configured to control a booster operation of the charge pump depending on the output voltage. A mode of the booster operation includes a charge mode that charges the output capacitor and a discharge mode that discharges the output capacitor. The mode is switched depending on the output voltage. The feedback circuit section includes a booster operation control section configured to secure a period during which the mode is not switched between the charge mode and the discharge mode in accordance with an external synchronizing signal. The period includes a timing at which an active scan line is switched among the plurality of scan lines.
