Abstract: A display apparatus includes a substrate including a data line extending in a first direction, a voltage line extending in the first direction, and a first circuit disposed in a non-display area and electrically connected to the data line and the voltage line, wherein the first circuit includes a thin-film transistor including a semiconductor layer and a gate electrode overlapping a semiconductor layer, where one side of the semiconductor layer is electrically connected to the data line and another side is electrically connected to the voltage line, a first capacitor including a first lower electrode not overlapping the semiconductor layer and a first upper electrode on the first lower electrode, and a second capacitor including a second lower electrode not overlapping the semiconductor layer and a second upper electrode on the second lower electrode, and the gate electrode is at a same layer as the data line and the voltage line.
