Shift register, gate driving circuit, display panel and display device
Disclosed are a shift register, gate electrode driving circuit, display panel and display device. The shift register includes a second output module and a coupling module, the coupling module having two ends electrically connected to a third node and a second signal output end respectively. In a second phase, a potential at a fourth node is an enable level, the second output module transfers a high-level signal at a first power source signal input end to a second output end; in a third phase, a potential at the third node is the enable level, the second output module transfers a low-level signal at a second power source signal input end to the second output end; the low-level signal at the second output end is coupled to the third node through a coupling function of the coupling module, the potential at the third node is then lower in the third phase than in the second phase.
