Abstract
A thin film transistor, in one or more examples, includes a semiconductor layer, an upper gate electrode overlapped with the semiconductor layer, an upper insulating layer disposed between the semiconductor layer and the upper gate electrode, a first lower gate electrode overlapped with the semiconductor layer, a second lower gate electrode disposed between the semiconductor layer and the first lower gate electrode, overlapped with the semiconductor layer, and configured to have a width smaller than that of the upper gate electrode, a first lower insulating layer disposed between the first lower gate electrode and the second lower gate electrode, and a second lower insulating layer disposed between the second lower gate electrode and the semiconductor layer. A display apparatus including a thin film transistor is also disclosed.
