Abstract: A display device includes a display panel including data lines, scan lines, and pixels, a scan driver configured to provide a scan signal to the pixels through the scan lines, a data driver configured to provide data signal to the pixels through the data lines, a voltage generator configured to provide an on-bias voltage to the pixels through the data lines, a timing controller configured to generate a first control signal that controls the data driver and a second control signal that controls the voltage generator, and a protection circuit configured to generate a first protection signal and a second protection signal and prevent an overlapping output of the data signal and the on-bias voltage based on the first control signal and the second control signal.
