Abstract: A display apparatus is provided including a display area and a non-display area. The display area includes a display element and the non-display area includes a pad portion. A first thin-film transistor (TFT) is arranged in the display area. The first TFT includes silicon and a first gate electrode. A second TFT is arranged on a first insulating layer covering the first gate electrode and includes an oxide and a second gate electrode. A first voltage line extends in a first direction. A data line is spaced apart from the first voltage line. A connection wire is disposed in the display area and connects the data line to the pad portion. The connection wire includes a first portion extending in the first direction and a second portion extending in a second direction crossing the first direction, and the first portion overlaps the first voltage line.
