Abstract
A gate driving circuit according to an embodiment and a display panel including the same are disclosed. The gate driving circuit according to the embodiment includes: a controller configured to charge and discharge a first control node that pulls up an output voltage and a second control node that pulls down the output voltage; an output unit including a pull-up transistor configured to apply a gate high voltage to an output node in response to a charging voltage of the first control node, and a pull-down transistor configured to apply a gate low voltage to the output node in response to a charging voltage of the second control node; a sensing unit configured to sense a threshold voltage of the pull-down transistor; and a compensation unit configured to change the charging voltage of the second control node in response to an output of the sensing unit.
