    Abstract: The disclosure relates to a display panel, a display device, and a gate driver circuit. According to an embodiment, a display panel includes a gate driver circuit in which when a display device operates at low-speed for a long time, a voltage of a Q node between an input and an output of a gate shift register in a gate driver circuit does not rise but is maintained at a value below a certain voltage. Here, potential maintaining circuit (PMC) is connected to a Q node, a Q2 node, or a vulnerable node between an input unit and an output unit of the gate shift register. The PMC maintains a potential of the Q node at a value below a selected level during a light-emitting operation for display. Thus, image quality defect due to damage to output voltage resulting from leakage and noise at an output node is prevented.
