Abstract
An object of the present invention is to further reduce the power consumption of a display device adopting pause driving. In a display device that includes a display driving unit () that drives a display unit (); and a power supply circuit () that generates a plurality of operation voltages to be supplied to the display driving unit (), and performs pause driving that repeats a scanning period during which gate bus lines (GL) are scanned and a pause period during which the scanning of the gate bus lines (GL) is stopped, the display driving unit () provides a control signal (SM) indicating whether the current point in time is the scanning period or the pause period, to the power supply circuit (), and the power supply circuit () makes the voltage value of at least one of the plurality of operation voltages supplied to the display driving unit () smaller during the pause period than during the scanning period, based on the control signal (SM).
