A display panel includes an array substrate, an opposite substrate, and at least one closed sealing element. The array substrate has a first through hole, and the array substrate includes a plurality of pixel units, a plurality of scan lines, and a plurality of data lines. The scan lines are electrically connected to the pixel units. The data lines intersect with the scan lines, and the data lines are electrically connected to the corresponding pixel units. The opposite substrate is disposed opposite to the array substrate, and the opposite substrate has a second through hole. The closed sealing element is disposed between the array substrate and the opposite substrate, and the closed sealing element has a third through hole. The first through hole, the second through hole, and the third through hole form an opening.

Display panel and display device

A gate-on array shift register includes a signal-input unit, a control transistor and at least three stable modules. The signal-input unit receives and outputs a previous-stage output signal. The control terminal of the control transistor is electrically coupled to the signal-input unit for receiving the previous-stage output signal. The control transistor outputs corresponding output signal on output terminal of the shift register according to the previous-stage output signal. Each of the stable modules is electrically coupled to the control terminal of the control transistor and the output terminal of the shift register to stabilize voltage of the terminals.
