Abstract: A display device and a gate driving panel circuit including the same are discussed. The gate driving panel circuit in an example includes an output buffer block configured to receive a clock signal and output a scan signal, and a logic block configured to control respective voltages of a Q node and a QB node electrically connected to the output buffer block. The output buffer block includes a pull-up transistor disposed between a clock node to which the clock signal is input and an output node to which the scan signal is output, and a pull-down transistor disposed between a gate low voltage node to which a gate low voltage is applied and the output node. A gate node of the pull-up transistor is electrically connected to the Q node.
