1. A display substrate, comprising:
a base substrate comprising a display area and a frame area located on at least one side of the display area;
a plurality of shift registers located in the frame area and arranged in cascade;
a plurality of jumper terminals located between the shift registers and the display area and comprising first jumper terminals and second jumper terminals, wherein the first jumper terminals are electrically connected to the shift registers, and the second jumper terminals are located between a layer where the first jumper terminals are located and the base substrate;
a plurality of transfer terminals located between the shift registers and the display area, and located on a side of the layer where the first jumper terminals are located away from the base substrate; and
an insulating layer located in the display area and the frame area, located between a layer where the second jumper terminals are located and a layer where the plurality of transfer terminals are located, and comprising one channel exposing the first jumper terminals and the second jumper terminals; wherein a first jumper terminal and a second jumper terminal of a same jumper terminal are directly overlapped with a same transfer terminal respectively in the one channel;
wherein the first jumper terminal comprises a first side surface close to the second jumper terminal and a first upper surface; the second jumper terminal comprises a second side surface close to the first jumper terminal and a second upper surface;
the first jumper terminal and the second jumper terminal of the same jumper terminal are directly overlapped with the same transfer terminal respectively in the one channel, which comprises:
the transfer terminal is in direct contact with at least a part of the first upper surface of the first jumper terminal and the first side surface of the first jumper terminal; in an area between the first jumper terminal and the second jumper terminal, the transfer terminal is in direct contact with at least a part of a third upper surface of the base substrate; and the transfer terminal is in direct contact with the second side surface of the second jumper terminal and at least a part of the second upper surface of the second jumper terminal.
