Abstract
A display substrate, a method for forming the display substrate and a display device are provided. The display substrate includes: a first conductive pattern located on a base substrate, where a ring-shaped conductive protection structure is arranged at an edge of a preset region of the first conductive pattern and surrounds the preset region, and the conductive protection structure is made of an anti-dry-etching material; an insulation layer covering the first conductive pattern; and a second conductive pattern located on a side of the insulation layer away from the first conductive pattern, where the second conductive pattern is electrically connected to the first conductive pattern through the via-hole.
