Abstract
A display panel includes a substrate, and a pixel array and a gate driving circuit. The gate driving circuit provides gate driving signals to the pixel array, and includes shift registers, wherein each shift register includes a voltage providing unit, a first driving transistor, a voltage transmitting unit and a second driving transistor. The voltage providing unit receives a setting signal and a system high voltage to provide a first terminal voltage. The first driving transistor receives a first clock signal and the first terminal voltage to provide a first gate driving signal. The voltage transmitting unit receives the first gate driving signal to provide a second terminal voltage. The second driving transistor receives a second clock signal and the second terminal voltage to provide a second gate driving signal. Therefore, the influence caused by large difference of driving capabilities of the first and the second driving transistor is avoided.
