A gate driving apparatus includes a first stage which outputs a first gate output signal, and a second stage which outputs a second gate output signal. The first stage includes: a transistor which includes a gate electrode, a source electrode and a drain electrode; and a dummy transistor which includes a dummy gate electrode, a dummy source electrode and a dummy drain electrode. The gate electrode receives the second gate output signal, and the dummy source electrode is connected to the source electrode or the drain electrode of the transistor and prevents static electricity from flowing to the first stage.

Gate-driving apparatus and display device including the same

A display substrate includes a base substrate, a plurality of a gate line, a gate driving circuit, a starting pad and a first electrostatic dispersion portion. The gate lines are disposed at a display area of the base substrate and extend to the peripheral area. The gate driving circuit is disposed at a peripheral area of the base substrate, includes a plurality of a stage connected to the gate lines, and provides the gate lines with gate signals. The gate driving circuit is driven in response to a vertical starting signal applied to a first stage of the plurality of stages. The starting pad is disposed at the peripheral area and applies the vertical starting signal to the gate driving circuit. The first electrostatic dispersion portion is electrically connected to the starting pad. The first electrostatic dispersion portion disperses electrostatic applied to the gate driving circuit.
