Abstract
The application discloses a thin film transistor and a light-emitting diode (LED) backplane. The thin film transistor includes: a first gate, a first insulating layer, a first source, a semiconductor layer, a first drain, a second insulating layer, and a second gate; the first insulating layer covers the first gate; the first source, the semiconductor layer, and the first drain are all disposed at a side of the first insulating layer away from the first gate; the second insulating layer covers the first drain, the semiconductor layer, and the first source; and the second gate is disposed on a surface of a side of the second insulating layer away from the first gate, wherein the first source, the semiconductor layer, and the first drain jointly constitute a vertical channel structure.
