Abstract
A display substrate includes: a base, and pixel units arranged in an array, each pixel unit including at least two sub-pixels each including: a pixel driving circuit, and a light-emitting element. The light-emitting element includes: a first electrode, a light-emitting layer, and a second electrode arranged on the base sequentially. Each sub-pixel is configured with a corresponding operating voltage transmission line. The pixel driving circuit includes: a driving transistor with a first pole electrically connected to the operating voltage transmission line. 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. The at least two sub-pixels include: at least one first sub-pixel and at least one second sub-pixel. The first and second sub-pixels are configured with first and second operating voltage transmission lines insulated from each other, respectively.
