Abstract
Provided are a gate driving circuit and a display device using the same. The gate driving circuit includes a shift register including a plurality of stages. A stage of the stages includes a first transistor configured to charge a first node with a first voltage level of a high voltage terminal of the stage. The first voltage level is higher than a second voltage level of a low voltage terminal of the stage. The stage further includes a control circuit connected to the first transistor. The control circuit is connected to the high voltage terminal and to an output terminal of a previous stage of the shift register. The control circuit is configured to control the first transistor to increase a voltage of the first node to be higher than a third voltage level, which is less than the first voltage level by a threshold voltage of the first transistor.
