Claim:
1. A thin film transistor, comprising a gate electrode, a gate insulating layer, a metal oxide semiconductor active layer, a source electrode and a drain electrode that are provided on a substrate; wherein, the metal oxide semiconductor active layer is disposed between the substrate and the source electrode and the drain electrode, and corresponds to a gap between the source electrode and the drain electrode; the thin film transistor further includes a first pattern and a second pattern that are disposed in the same layer and contact with the metal oxide semiconductor active layer; the first pattern corresponds to and contacts directly with the source electrode, and the second pattern corresponds to and contacts directly with the drain electrode; wherein, the first pattern and the second pattern each include a zinc oxide-based binary metal oxide, the metal oxide semiconductor active layer includes a zinc oxide-based multi-element metal oxide semiconductor, and the zinc oxide-based multi-element metal oxide is a metal oxide obtained by injecting metal doping ions into the zinc oxide-based binary metal oxide.
