Abstract:
Provided is a display apparatus including a substrate and a semiconductor layer including first and second semiconductor layers. A first gate insulating layer is formed on the semiconductor layer. A first gate wiring overlapping the first semiconductor layer is formed on the first gate insulating layer. A second gate insulating layer is formed on the first gate wiring. A second gate wiring overlapping the second semiconductor layer is formed on the second gate insulating layer. A third gate insulating layer covers the second gate wiring. A driving voltage line intersecting the first and second gate wirings is formed on the third gate insulating layer. A data line intersecting the first and second gate wirings is formed on the third gate insulating layer. A short circuit protection area is formed between the first gate wiring, the second gate wiring, the driving voltage line and the data line.
