1. A display device comprising:
a display panel including a gate line, a data line, and a pixel electrically connected to the gate line and the data line, wherein the display panel displays an image based on input image data;
a gate driver which outputs a gate signal to the gate line;
a data driver which outputs a data voltage to the data line; and
a power supply voltage generator which provides a driving voltage to the display panel, the gate driver and the data driver,
wherein the power supply voltage generator generates a gate clock signal based on an on-clock signal and an off-clock signal, and
the power supply voltage generator changes a count value of the on-clock signal or the off-clock signal in a way such that the gate clock signal is corrected into a normal signal, which allows the display panel to display the image, when the gate clock signal is an abnormal signal.
