Display substrate for double-sided display and manufacturing method thereof, display panel and display device

A method for manufacturing a display substrate, comprising:

• providing a base substrate having a first side and a second side opposite to each other;
• forming a transmitter on the first side of the base substrate, wherein the transmitter is configured to convert a first display electrical signal into a conduction signal;
• forming a first light-emitting element on a side of the transmitter away from the base substrate, wherein the first light-emitting element emits light under a driving action of the first display electrical signal;
• forming a receiver on the second side of the base substrate, wherein the receiver is configured to receive the conduction signal and convert the conduction signal into a second display electrical signal;
• and
• forming a second light-emitting element on a side of the receiver away from the base substrate, wherein the second light-emitting element emits light under a driving action of the second display electrical signal.
