A display device includes a display including pixels connected to a first power line, a second power line, scan lines, and data lines, a current sensor for sensing a global current value flowing to the pixels, a power generator for supplying a first driving power and a second driving power to the first and second power lines, and a timing controller for controlling the power generator so that a voltage rising time of the first driving power is changed in response to a differential voltage value corresponding to a difference between a voltage of the first driving power of a previous frame and a voltage of the first driving power of a current frame, and in response to a differential current value corresponding to a difference between the global current value and a maximum current value to flow to the pixels in response to a load of the display.
