Abstract
A display apparatus including a first thin film transistor disposed on a substrate and including a first active layer, a second thin film transistor disposed on the first thin film transistor and including a second active layer overlapping the first thin film transistor, a first planarization layer disposed between the first thin film transistor and the second thin film transistor, the first planarization layer including a first insulating layer and a second insulating layer disposed on the first insulating layer, and a first buffer layer disposed between the first planarization layer and the second thin film transistor, in which an upper surface of the second insulating layer and an upper surface of the first insulating layer are substantially flush with each other.
