Display substrate and display apparatus

A display substrate, comprising:

• a base, comprising:
• a display region, and a peripheral region surrounding the display region;
• a plurality of pixel units located in the display region and arranged in an array, each of which comprising at least two sub-pixels each comprising:
• a pixel driving circuit, and a light-emitting element, wherein the light-emitting element comprises:
• a first electrode, a light-emitting layer, and a second electrode arranged in sequence along a direction away from the base, wherein each sub-pixel is configured with a corresponding operating voltage transmission line, and the pixel driving circuit comprises:
• a driving transistor with a first pole electrically connected to the corresponding operating voltage transmission line, and a second pole electrically connected to the first electrode, the first electrode is located on a side of the driving transistor distal to the base, and the operating voltage transmission line is located between a layer structure where a control pole of the driving transistor is located and a layer structure where the first electrode is located;
• and
• the at least two sub-pixels comprise:
• at least one first sub-pixel and at least one second sub-pixel, wherein the first sub-pixel is configured with a first operating voltage transmission line, and the second sub-pixel is configured with a second operating voltage transmission line, and the first operating voltage transmission line is insulated from the second operating voltage transmission line.
