Display substrate, display panel and electronic device

A display substrate, having a display region, an encapsulation region located outside the display region and a peripheral region located between the display region and the encapsulation region;

• the display substrate comprising:
• a base substrate;
• a pixel definition layer disposed on a side of the base substrate;
• and
• a photo spacer layer disposed on a side of the pixel definition layer away from the base substrate;
• wherein the photo spacer layer includes a plurality of peripheral photo spacers disposed in the peripheral region;
• a direction perpendicular to a border of the display region adjacent to the plurality of peripheral photo spacers is a first direction;
• in the first direction, a distance from a peripheral photo spacer of the plurality of peripheral photo spacers closest to the encapsulation region to the encapsulation region is a first distance, and a distance from the peripheral photo spacer of the plurality of peripheral photo spacers closest to the encapsulation region to the display region is a second distance;
• and
• the first distance is less than or equal to the second distance.
