Abstract: The present application discloses a GOA circuit and a display panel. High-temperature durability of a first node is improved not only by adding a thirteenth transistor to a pull-down remaining module to lower a voltage difference between a source and a drain of the an eleventh transistor to suppress electric leakage of the first node, but also by adding a twentieth transistor to the pull-down remaining module to lower a voltage difference between a gate and a source of a nineteenth transistor to suppress electric leakage of the first node.

Abstract: A GOA device and a gate driving circuit are provided. A pull-up control unit and a bootstrap unit sequentially control a control node of an Nth stage GOA unit to be pulled up to a first high voltage level and a second high voltage level. A pull-up unit outputs a gate driving signal according to a change of a voltage level of the control node and a stage transfer signal of the Nth stage GOA unit. As such, a pulse width of the gate driving signal is increased, and the problem that the charging ability is not sufficient can be solved.

Abstract: The present invention provides a display panel and a display device. The display panel comprises a first substrate, a driving circuit layer, a first common electrode layer, and at least one scanning signal transmission line located between two adjacent data lines and arranged in parallel with the data lines. The scanning signal transmission line and the driving circuit layer are arranged in a same layer. The present invention reduces widths of frames and increases display aperture ratio by directing the scanning signal transmission line to a bottom edge of the display panel and setting the scanning signal transmission line in pixel units.
