Shift register, gate driving circuit and display panel for preventing channel short circuit

A shift register, comprising:

• at least one transistor;
• wherein each of the at least one transistor comprises a gate electrode, a gate insulating layer, an active layer, a first electrode and a second electrode;
• the first electrode and the second electrode are of comb-shaped structures;
• the first electrode comprises first comb tooth portions and second comb tooth portions arranged at intervals, and a first comb handle portion connecting the first comb tooth portions and the second comb tooth portions;
• and comb tooth electrodes of the first comb tooth portions have a different length from that of comb tooth electrodes of the second comb tooth portions;
• the second electrode comprises third comb tooth portions and fourth comb tooth portions arranged at intervals, and a second comb handle portion connecting the third comb tooth portions and the fourth comb tooth portions;
• and comb tooth electrodes of the third comb tooth portions have a different length from that of comb tooth electrodes of the fourth comb tooth portions;
• the first comb tooth portions and the third comb tooth portions form an inter-digital structure, the second comb tooth portions and the fourth comb tooth portions form an inter-digital structure, and orthographic projections of the first comb tooth portions, the third comb tooth portions, the second comb tooth portions and the fourth comb tooth portions on the active layer are not overlapped with each other;
• a gap between the comb tooth electrodes of the first comb tooth portion and the third comb tooth portion adjacent to each other is a first gap;
• a gap between the comb tooth electrodes of the second comb tooth portion and the fourth comb tooth portion adjacent to each other is a second gap;
• a gap between the first comb tooth portion and the second comb tooth portion is a third gap;
• the third gap is greater than the first gap, and the third gap is greater than the second gap;
• and
• an orthogonal projection of a part of the first comb handle portion on the active layer is one of a diagonal line and an arc.
