Abstract

The present disclosure provides a light-emitting substrate, a method for manufacturing the same, and a display device. The light-emitting substrate includes: a substrate including a light-emitting region; a first conductor on the substrate and at least in the light-emitting region, the first conductor extending along a first direction in the light-emitting region; a second conductor on the first conductor and arranged in the light-emitting region, the second conductor including a first connecting portion; and a first insulator within the light-emitting region. The first connecting portion extends along a second direction, an orthographic projection of the first connecting portion on the substrate at least partially overlaps with an orthographic projection of the first conductor on the substrate to constitute an overlapping region. The first insulator is only between the first connecting portion and the first conductor, the overlapping region is within an orthographic projection of the first insulator on the substrate.
