1. A display substrate, comprising a drive circuit layer disposed on a base substrate, wherein
the drive circuit layer comprises a plurality of circuit units, and a circuit unit comprises a pixel drive circuit and a data signal wire providing a data signal to the pixel drive circuit and an initial signal wire providing an initial signal;
the plurality of circuit units comprises at least one first circuit unit and at least one tracing circuit unit, the first circuit unit is provided with a first compensation line extending along a first direction and a second compensation line extending along a second direction, the tracing circuit unit is provided with a first data fan-out line extending along the first direction or a second data fan-out line extending along the second direction, the first data fan-out line or the second data fan-out line is connected with the data signal wire, and the first direction intersects with the second direction; and
an orthographic projection of the first compensation line in a plane of the display substrate is at least partially overlapped with an orthographic projection of the initial signal wire in the plane of the display substrate;
the first compensation line, the second compensation line, and the first data fan-out line are formed simultaneously through a same patterning process; or the first compensation line, the second compensation line, and the second data fan-out line are formed simultaneously through a same patterning process.
