Claim 11:
12. A manufacturing method of a thin film transistor, comprising:
forming an active layer;
forming a gate insulating layer on the active layer;
forming a gate electrode on one side of the gate insulating layer away from the active layer, and forming an opening in the gate electrode; and
performing a doping process on the active layer to form a first lightly doped region, a first heavily doped region and a second lightly doped region, which are sequentially arranged in a direction parallel to a plane where the active layer is located, in a part of the active layer overlapped with the opening,
wherein the opening comprises a first tend portion and a second end portion in a second direction perpendicular to the first direction, the active layer comprises a first edge and a second edge in the second direction, the first edge is at one side of the active, layer close to the first end portion, the second edge is at one side of the active layer close to the second end portion, the first edge is aligned with the first edge or located at an outer side of the first edge, and the second end portion is aligned with the second edge or located at an outer side of the second edge.
