Display substrate, method for manufacturing display substrate, and display device

A method for manufacturing the display substrate, comprising a step of forming a compensation capacitor;

• wherein the display substrate comprises a base substrate, a driving circuit layer and a light-emitting unit, wherein the driving circuit layer and the light-emitting unit are located on the base substrate, the light-emitting unit comprises a first electrode, a second electrode, and a light-emitting layer located between the first electrode and the second electrode, the display substrate comprises a first display region, a second display region, and an opening region, the second display region is located between the first display region and the opening region, a pixel density of the first display region is greater than a pixel density of the second display region, and the compensation capacitor is configured for compensating a sub-pixel in the second display region;
• and one of the plates of the compensation capacitor is electrically connected to the gate electrode of the sub-pixel in the second display region, and the other one of the plates is electrically connected to the first electrode;
• the driving circuit layer comprises a gate layer;
• wherein in a direction away from the base substrate, the gate layer of the driving circuit layer comprises a first gate metal layer and a second gate metal layer, one plate of the first plate and the second plate of the compensation capacitor is provided in a same layer and made of a same material as the first gate metal layer, and the other plate of the compensation capacitor is provided in a same layer and made of a same material as the second gate metal layer.
