    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.

    A gate driving circuit is provided. The gate driving circuit includes multistage driving modules, where an Nth stage driving module includes a setting circuit, a first driving circuit, an isolating switch circuit, a second driving circuit and an anti-noise circuit. The setting circuit generates a first precharge signal according to a gate driving signal of an (N−2)th scan line or a start signal. The isolating switch circuit coupled between the first driving circuit and the second driving circuit provides a second precharge signal, so as to effectively avoid a flickering problem of a display image caused by a surge of the gate driving signal due to a coupling effect of a parasitic capacitance of the transistor and a bootstrap capacitor, and meanwhile the bootstrap capacitor is not used, so as to effectively reduce a bezel area.
