Abstract
Display substrate, method for manufacturing the same and display device are provided. The display substrate includes a base substrate comprising a hole region, an isolation region surrounding the hole region, and a display region surrounding the isolation region. At least one isolation pillar is provided within the isolation region, and each isolation pillar is arranged at a perimeter surrounding the hole region. A light-emitting layer covering the isolation pillar is provided in the display region and the isolation region, and the isolation pillar separates the light-emitting layer located between the hole region and the display region. The isolation pillar includes: a plurality of layers of metal patterns sequentially arranged in a stack on the base substrate; and an insulating film layer which is a layer stack covering the metal patterns and has a shape conforming to shapes of the metal patterns. The display substrate, the method for manufacturing the same, and the display device provided by the present disclosure enables reduced masks, reduced costs and simplified process.
