Abstract: A display device includes a display panel and a gate driver. The gate driver includes an N-th stage (where N is a natural number) configured to output an N-th scan gate signal and output an N-th sensing gate signal. The N-th stage includes a compensator, a sixth transistor including a control electrode connected to a first node, and a ninth transistor including a control electrode connected to the first node. In a variable frequency mode, the compensator outputs a second signal to the first node in response to a first signal, and the sixth transistor does not output the N-th scan gate signal when the ninth transistor outputs the N-th sensing gate signal based on the sensing clock signal, the voltage of the first node, and the voltage of the second node.
