Abstract
A method for manufacturing a display substrate, a display substrate, a display panel and a display device are provided. The method includes: disposing a mask plate including an occlusion area above a base substrate, an orthographic projection of occlusion area on the base substrate partially overlapping a folding area of the base substrate; forming an inorganic layer pattern with an opening on the base substrate by using mask plate, an orthographic projection of opening on the base substrate partially overlapping the folding area of base substrate. An orthographic projection of opening on the base substrate partially overlaps the folding area of base substrate. The folding area of base substrate is occluded by mask plate. The inorganic layer is formed on the base substrate by using mask plate. Effect of conveniently and quickly removing a portion the inorganic layer located in the folding area can be achieved without removing the portion.
