Display substrate and display apparatus

A display substrate, comprising:

• a base substrate, comprising a display region and a peripheral region located at a periphery of the display region;
• wherein the display region comprises a first display region and a second display region, and the first display region at least partially surrounds the second display region;
• a circuit structure layer located on the base substrate, comprising a plurality of pixel circuits, at least one first trace extending along a first direction, at least one second trace extending along a second direction, and at least one third trace located in the peripheral region;
• wherein the first direction and the second direction intersect;
• the plurality of pixel circuits, the first trace, and the second trace are located in the first display region;
• and
• a light emitting structure layer located on a side of the circuit structure layer away from the base substrate, comprising a plurality of first light emitting elements located in the first display region and a plurality of second light emitting elements located in the second display region, wherein:
• the plurality of pixel circuits comprises a plurality of first pixel circuits and a plurality of second pixel circuits;
• at least one first pixel circuit in the plurality of first pixel circuits is electrically connected with at least one first light emitting element in the plurality of first light emitting elements, and at least one second pixel circuit in the plurality of second pixel circuits is electrically connected with at least one second light emitting element in the plurality of second light emitting elements;
• the at least one first trace is electrically connected with the at least one second trace, and the at least one third trace is electrically connected with at least one of following:
• the at least one first trace and the at least one second trace;
• and
• an orthographic projection of the at least one first trace on the base substrate is located between two adjacent rows of pixel circuits.
