1. A display substrate, comprising:
a base substrate comprising a special-shaped display area and a frame area located on at least one side of the special-shaped display area; wherein the special-shaped display area comprises a first display area and a second display area located on at least one side of the first display area, and the second display area is arranged in contact with the frame area;
a data line located on the base substrate and located in the first display area and the second display area;
a plurality of fan-out lines located on a side of a layer where the data line is located away from the base substrate, and located in the first display area, wherein at least one of the plurality of fan-out lines is electrically connected to the data line; and
a plurality of dummy leads arranged in a same layer as the plurality of fan-out lines and located in the second display area, wherein a ratio of a distribution density of the plurality of dummy leads in the second display area to a distribution density of the plurality of fan-out lines in the first display area satisfies a preset threshold.
