Abstract: A display apparatus including a gate driving circuit configured to include a plurality of stages connected to each other one after another. An i-th stage of the stages includes an output transistor and a control part. At least one control transistor included in the control part includes a first control electrode to which a switching control signal is applied, and a second control electrode disposed on a layer different from a layer on which the first control electrode is disposed, and to which a reference voltage is applied.
