description | Disclosed are a gate driving circuit capable of reducing stress applied to a pull-down transistor, and a display panel including the same. The gate driving circuit according to an embodiment of the present disclosure includes: a control unit which charges and discharges a first control node pulling up an output voltage and a second control node pulling down the output voltage; an output unit including a pull-up transistor which applies a gate-high voltage to an output node in response to a charging voltage of the first control node, and a pull-down transistor which applies a gate-low voltage to the output node in response to a charging voltage of the second control node; a sensing unit which senses a threshold voltage of the pull-down transistor; and a compensation unit which changes the charging voltage of the second control node in response to an output of the sensing unit.
