Abstract: A display apparatus includes a substrate, a thin film transistor, a first inorganic insulating layer, a first organic insulating layer, a second inorganic insulating layer, and a second organic insulating layer. The thin film transistor is over the substrate and includes a semiconductor layer and a gate electrode. The first inorganic insulating layer includes a first insulating layer between the semiconductor layer and the gate electrode of the thin film transistor and a second insulating layer over the gate electrode. The first organic insulating layer is over the first inorganic insulating layer. The second inorganic insulating layer is over the first organic insulating layer. The second organic insulating layer is over the second inorganic insulating layer. At least one hole passing through the first inorganic insulating layer and the second inorganic insulating layer is formed in a peripheral portion of the thin film transistor.
