Display substrate and display device

A display device, comprising a display substrate;

• wherein the display substrate comprises:
• a base substrate, a plurality of data lines and sub-pixels on the base substrate;
• wherein the sub-pixel comprises a sub-pixel driving circuit and a light-emitting element;
• the sub-pixel driving circuit comprises a driving transistor and a data writing transistor, and the light-emitting element comprises a first electrode;
• a second electrode of the driving transistor is coupled to the corresponding first electrode through a first connection structure;
• a first electrode of the data writing transistor is coupled to the corresponding data line through a second connection structure;
• the first connection structure and the second connection structure are in a non-aperture region of the sub-pixel;
• and an orthographic projection of the first connection structure onto the base substrate and an orthographic projection of the second connection structure onto the base substrate are arranged along a first direction;
• the orthographic projection of the second connection structure onto the base substrate and an aperture region of the sub-pixel are arranged along a second direction, and the second direction intersects the first direction.
