Abstract
A gate driving circuit includes a stage which outputs a scan signal based on a scan clock signal, a voltage of a first node, and a voltage of a second node, and outputs a sensing signal based on a sensing clock signal, a voltage of the first node, and a voltage of the second node. The stage includes a second sensing portion including transistors electrically connected in series and a first pull-up control portion including transistors electrically connected in series, the transistors including control electrodes electrically connected to each other. A first intermediate node between the transistors of the second sensing portion is separated from a second intermediate node between the transistors of the first pull-up control portion.
