1. A display device, comprising:
a display panel including a plurality of pixels;
a gate driver which provides a gate signal to corresponding pixels of the plurality of pixels;
a data driver which provides a data voltage to the corresponding pixels of the plurality of pixels;
a power voltage generator which provides a pixel power voltage to each of the plurality of pixels, and provides a gate power voltage to the gate driver; and
a controller which provides a gate control signal to the gate driver,
wherein the pixel power voltage, the data voltage, and the gate control signal sequentially have a ground voltage level in response to a power-off signal so that a scan clock signal, a sensing clock signal and a carry clock signal of the gate control signal only have the ground voltage level after the data voltage has the ground voltage level.
