Claim:
1. A thin film transistor, comprising a gate, an active layer located on the gate, an ohmic contact layer located on the active layer, and a first electrode and a second electrode located on the ohmic contact layer, wherein the first electrode and the second electrode are partially overlapped with the active layer, and the ohmic contact layer is located within a region where the first electrode and the second electrode are overlapped with the active layer, wherein, the active layer is partially overlapped with the gate, and the active layer comprises at least one opening region which is partially overlapped with the gate and wherein the at least one opening region is provided inside the active layer so that the active: layer forms a closed loop; and the first electrode and/or the second electrode extends beyond the active layer through the at least one opening region, and is overlapped with the active layer outside the gate.
