Abstract
A display substrate includes a base, a voltage signal line, a driving circuit structure, a cathode overlapping layer and a cathode layer. The voltage signal line is located in the non-display region and is arranged around the display region. The driving circuit structure is located in the non-display region, and is located at a side of the voltage signal line proximate to the display region in a first direction. The cathode overlapping layer is located in the non-display region and is arranged around the display region. At least a part of a surface of a first portion of the cathode overlapping layer proximate to the base is in electrical contact with a corresponding part of the voltage signal line. An orthographic projection of a second portion of the cathode overlapping layer on the base at least partially overlaps an orthographic projection of the driving circuit structure on the base.
