  • Publication number: 20230186825
    Abstract: Disclosed is a gate driving circuit comprising a plurality of stage circuits dependently connected to each other and configured to output ‘j’ output signals ('j? is an integer of 2 or more), wherein each of the plurality of stage circuits includes a logic controller for controlling a voltage of each of first and second nodes, and an output circuit unit for outputting each of ‘j’ clock signals as the ‘j’ output signal in response to the voltage of the first node, wherein the output circuit unit includes ‘j’ output buffers for outputting each of the ‘j’ clock signals as the ‘j’ output signal through an output node in response to the voltage of the first node, and a capacitor prepared between the first node and the output node of some of the ‘j’ output buffers.
