Claim 0:
1. A display substrate, comprising:
a base substrate, and
a plurality of sub-pixels on the base substrate,
wherein each of the plurality of sub-pixels comprises a pixel circuit, a first connection electrode and a pixel electrode, and the first connection electrode is connected with the pixel circuit and is electrically connected with the pixel electrode through a first via hole; pixel circuits of the plurality of sub-pixels are distributed in a plurality of columns in a first direction and a plurality of rows in a second direction;
the plurality of sub-pixels comprise a first sub-pixel and a second sub-pixel adjacent in the second direction; a height of an orthographic projection of the first via hole of the first sub-pixel on the base substrate and a height of an orthographic projection of the first via hole of the second sub-pixel on the base substrate are different in the first direction;
the display substrate further comprises a plurality of first power lines extended along the first direction, a second power line extended along the second direction and on a side of the plurality of first power lines away from the base substrate,
wherein the plurality of first power lines are connected with the plurality of pixel circuits to provide a first power voltage;
the display substrate further comprises a plurality of third power lines which are extended along the first direction and are electrically connected with the plurality of first power lines in one-to-one correspondence respectively, and each of the plurality of third power lines is at least partially overlapped with the corresponding first power line in the direction perpendicular to the base substrate; and
the plurality of third power lines and the second power line are in a same layer and are of an integral structure.
