Abstract: A display device is disclosed that includes a display panel including a plurality of pixels configured to receive an initialization voltage through an initialization voltage line, a controller configured to output a voltage control signal for controlling a voltage level of the initialization voltage, and a power manager configured to provide the initialization voltage to the initialization voltage line, change the voltage level of the initialization voltage to an initialization level at or after a power-on time at which a power starts to be supplied and before a display-on time at which an image starts to be displayed based on the voltage control signal, and change the voltage level of the initialization voltage to a target level corresponding to a luminance of the image at or after the display-on time based on the power control signal.
