Abstract: Provided are a gate driving circuit and a display device including the same. The gate driving circuit includes a first controller configured to control a first control node to act as a pull-up control node to turn on a first transistor when an activation clock is input to the first controller for a first unit time, and to be deactivated when a deactivation clock is input thereto for a second unit time; and a second controller configured to control a second control node to act as a pull-up control node to turn on a second transistor when the activation clock is input to the second controller for the second unit time, and to be deactivated when the deactivation clock is input thereto for the first unit time.
