Abstract: A display device includes a signal line drive circuit provided with an analog amplifier through which a stationary electric current flows. The display device further includes a control signal output section which suspends operation of the analog amplifier during a period (non-scanning period) from an start time after application to a data signal line S(i) of a voltage necessary for display is completed in a horizontal period to an end time in the horizontal period. The control signal output section sustains an AMP_Enable signal through which the analog amplifier is controlled at an L value (a low value) in the non-scanning period. As a result, stationary electric current flowing through the analog amplifier is cut off in the non-scanning period. According to this, the display device allows for reduction of electric power consumption while being capable of displaying a moving image without causing flickering.
