Abstract
A gate driving circuit includes: a plurality of driving stages configured to apply gate signals to a plurality of pixels of a display panel, one driving stage of the driving stages including: a thin film transistor including a first control electrode, an active part overlapping the first control electrode, an input electrode overlapping the active part, an output electrode overlapping the active part, and a second control electrode on the first control electrode and the active part; and a control voltage generator configured to supply a control voltage determined according to a channel characteristic of the thin film transistor to the second control electrode and to include a voltage generating thin film transistor including an active part having a same channel characteristic as the active part of the thin film transistor.
