1. A display device comprising:
a display panel including pixels displaying images;
a display panel driving circuit outputting a drive signal for driving the display panel;
a compensation signal generator sensing a noise signal generated by the display panel or the display panel driving circuit and generating a noise compensation signal corresponding to the noise signal; and
a level shifter which sequentially outputs a plurality of clock signals to clock lines,
wherein the compensation signal generator comprises:
a detection unit detecting a phase shift signal generated by synthesizing the plurality of clock signals; and
an inversion unit generating a phase inversion signal by inverting a phase of the phase shift signal.
