Display substrate and display device

A display substrate, comprising:

• a base substrate and a plurality of sub-pixels arranged on the base substrate, wherein the sub-pixels includes a sub-pixel driving circuit, an orthographic projection of the sub-pixel driving circuit on the base substrate has a maximum first width along a second direction;
• the display substrate further includes:
• an initialization signal transmission layer arranged on the base substrate;
• wherein the initialization signal transmission layer includes a plurality of first transmission portions and a plurality of second transmission portions;
• the plurality of first transmission portions are arranged along a first direction, the first transmission portion includes at least a portion extending along the second direction, the second direction intersects the first direction;
• the second transmission portion includes at least a portion extending along the first direction, adjacent first transmission portions are coupled through at least one second transmission portion;
• the plurality of first transmission portions include a target transmission portion, and the target transmission portion includes at least a portion extending along the second direction, a second transmission portion located between the target transmission portion and an adjacent previous first transmission portion and a second transmission portion located between the target transmission portion and an adjacent next first transmission portion are staggered by a first distance along the second direction, the first distance is greater than or equal to the first width.
