摘要： A gate driving circuit includes a plurality of stages for providing gate signals, wherein a k-th stage (k is a natural number greater than 3) includes a first output transistor including a control electrode connected to a first node, an input electrode for receiving a clock signal, and an output electrode for outputting a k-th gate signal, a second output transistor including a control electrode connected to the first node, an input electrode for receiving the clock signal, and an output electrode for outputting a k-th carry signal, a pull-down unit connected to a discharge node to pull down the output electrode of the first output transistor in response to a signal of the discharge node, and a discharge unit configured to output a (k−1)-th carry signal output from a (k−1)-th stage to the discharge node in response to a (k+1)-th carry signal output from a (k+1)-th stage.

摘要： Provided is a gate driving unit including: a plurality of stages configured to be activated sequentially so as to generate gate signals; and a plurality of repair blocks having sizes smaller than the corresponding stages and configured to repair defects of the stages. Each of the repair blocks is disposed proximate to two or more stages so as to be configured to repair defects in the two or more stages.
