Abstract: A display substrate and a display device are provided. The display substrate includes: a base substrate, data lines and sub-pixels on the base substrate. The sub-pixels include a sub-pixel driving circuit and a light-emitting element including a first electrode. The sub-pixel driving circuit includes a driving transistor and a data writing transistor having a first electrode coupled to the data line through a second connection structure. A second electrode of the driving transistor is coupled to the first electrode through a first connection structure. The first and second connection structures are in a non-aperture region of the sub-pixel. Orthographic projections of the first and second connection structures onto the base substrate are arranged along a first direction. An orthographic projection of the second connection structure onto the base substrate and an aperture region of the sub-pixel are along a second direction which intersects the first direction.
