Abstract:
A display device is provided that includes a display panel including one or more sub-pixels and a gate driving circuit supplying a gate signal to the sub-pixels through gate lines, the gate driving circuit including a gate output buffer circuit including a pull-up transistor that controls a connection between a clock input node and a gate output node, and a pull-down transistor that controls a connection between a low level voltage node and the gate output node, a control circuit capable of controlling the gate output buffer circuit, and a dummy pull-down transistor whose a gate node is shared with a gate node of the pull-down transistor.
