Abstract

An embodiment of a display apparatus includes a substrate, a buffer layer on the substrate, a thin film transistor including a semiconductor layer disposed on the buffer layer and including a silicon semiconductor, and a gate electrode insulated from the semiconductor layer, and an insulating layer covering the semiconductor layer, in which a concentration of fluorine at an interface between the semiconductor layer and the buffer layer is at least 10% of a concentration of the fluorine at the interface between the semiconductor layer and the insulating layer.
