Claim:
1. A thin film transistor, comprising a gate electrode, a source electrode, a drain electrode and an active layer, wherein the source electrode and the drain electrode are disposed on two sides of the active layer respectively, and the source electrode, the drain electrode and the active layer are disposed in a same layer; and the thin film transistor further comprises a passivation shielding layer, and a width of the passivation shielding layer and that of the active layer are substantially identical along a direction of a connecting line between the source electrode and the drain electrode, wherein along the direction of the connecting line between the source electrode and the drain electrode, a width of the active layer and that of the gate electrode are identical, and wherein the passivation shielding layer contacts said same layer from outside of said same layer.
