Display substrate, display panel and display apparatus

A display substrate having a plurality of pixel regions;

• the display substrate comprising:
• a base;
• an accommodating layer disposed on the base;
• the accommodating layer being provided with a contact hole and a plurality of depressions that are located in a pixel region, the plurality of depressions being located on a periphery of the contact hole, and each depression being spaced apart from the contact hole;
• in a direction perpendicular to the base, the plurality of depressions and the contact hole penetrating the accommodating layer;
• an electrical connection structure disposed on the base, and a portion of the electrical connection structure passing through the contact hole;
• and
• a light-emitting layer disposed in each depression;
• wherein
• in position points of a side of an orthogonal projection of the contact hole on the base, a position point with a shortest distance from a wall of at least one depression located on the periphery of the contact hole is a first position point;
• an orthogonal projection of the contact hole on the base and orthogonal projections of the plurality of depressions on the base are in a shape of approximate polygon, the first position point is not located at a corner of the approximate polygonal orthogonal projection of the contact hole on the base, and a side of the orthogonal projection of the contact hole on the base closest to the depression is not parallel to at least one side(s) of the orthogonal projection of the depression on the base proximate to the contact hole.
