A display panel includes a substrate, a pixel array, and a plurality of shift registers. The pixel array is disposed on the substrate. The shift registers are disposed on the substrate for sequentially outputting a plurality of scanning signals to drive the pixel array. Each of the shift registers includes a pull-up transistor and a first reserve transistor. The pull-up transistor raises the voltage level of the corresponding scanning signal. A control terminal of the first reserve transistor is coupled to a control terminal of the pull-up transistor, and a second terminal of the first reserve transistor is coupled to a second terminal of the pull-up transistor. When the pull-up transistor in each of the shift registers has insufficient output ability, a first terminal of the first reserve transistor is coupled to a first terminal of the pull-up transistor. |
