Claim 0:
1. A thin film transistor, comprising:
an active layer;
a gate insulating layer at one side of the active layer;
a gate electrode at one side of the gate insulating layer away from the active layer,
wherein the gate electrode comprises an opening, and a part of the active layer overlapped with the opening comprises a first lightly doped region, a first heavily doped region and a second lightly doped region which are sequentially arranged in a first direction parallel to a plane where the active layer is located, and
wherein the opening comprises a first end 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 end portion is located at an outer side of the first edge, and the second end portion is located at an outer side of the second edge.
