Abstract
Gate driving circuit, display panel and display device are provided. The gate driving circuit includes a plurality of cascaded shift registers. A shift register of the plurality of shift registers includes an input module, a node control module, a first coupling module, a second coupling module and an output module. The input module is configured to adjust potentials of a first node and a second node. The node control module is configured to adjust potentials of a third node and a fourth node. The first coupling module includes a first switch unit and a first capacitor. The second coupling module includes a second capacitor placed between, and connected to, the fourth node and a shift output end. The output module is configured to control a signal at the shift output end. A capacitance of the second capacitor differs from a capacitance of the first capacitor.
