Thin film transistor and method for repairing the same, GOA circuit and a display device

摘要

The present disclosure provides a thin film transistor and method for repairing the same, GOA circuit and a display device, which aims to solve the problem that the source and/or drain of thin film transistor can not be repaired once it is short circuited with other conductive functional layers. The thin film transistor comprises a source, a drain, and a gate. The source and the drain have a comb shape and respectively comprise a plurality of comb-tooth portions and comb-handle portions for connecting each comb-tooth portion, and the gate is insulated from the source and the drain. Comb-tooth portions of the source are arranged by an interval with respect to comb-tooth portions of the drain. The comb-handle portion of the source and the gate do not overlap in their projections in the vertical direction, and the comb-handle portion of the drain and the gate do not overlap in their projections in the vertical direction.

1. A thin film transistor, comprising a source, a drain, and a gate, the source and the drain having a comb shape and respectively comprising a plurality of comb-tooth portions and comb-handle portions for connecting each comb-tooth portion, the gate being insulated from the source and the drain, and an active layer below the source and the drain,
wherein comb-tooth portions of the source are arranged by an interval with respect to comb-tooth portions of the drain, and wherein the comb-handle portion of the source and the gate do not overlap in their projections in the vertical direction, and the comb-handle portion of the drain and the gate do not overlap in their projections in the vertical direction, wherein a projection of the active layer in the vertical direction is located within a projection of the gate in the vertical direction, and wherein two edges of the active layer at both sides with respect to its extending direction extend to ends of the comb-tooth portions of the source and ends of the comb-tooth portions of the drain, respectively.
