Display substrate and display device

A display substrate comprising:

• a substrate and a plurality of sub-pixels arrayed on the substrate, a data signal line pattern electrically connected to at least one of the plurality of sub-pixels, wherein the plurality of sub-pixels comprises:
• a first sub-pixel and a second sub-pixel alternately arranged along a second direction;
• the first sub-pixel and the second sub-pixel each comprises:
• a power signal line pattern, at least part of the power signal line pattern extending along the second direction;
• a power compensation pattern, at least part of the power compensation pattern extending along the first direction, wherein the power signal line pattern and the power compensation pattern are both located on a side of the data signal line pattern close to the substrate,
• the power compensation pattern is electrically connected to the power signal line pattern and a power signal line pattern in an adjacent sub-pixel along the first direction;
• and
• an orthographic projection of the power signal line pattern on the substrate at least partially does not overlap an orthographic projections of the data line pattern on the substrate.
