Abstract: The present disclosure provides a display substrate and a method for manufacturing the same and a display device. The display substrate includes: sub-pixels disposed on a base substrate and each including a sub-pixel aperture area, a reflective layer, an insulating layer, independent anode patterns, a light-emitting function layer and a cathode. An orthographic projection of the reflective layer onto the base substrate at least partially overlaps an orthographic projection of the sub-pixel aperture area onto the base substrate. The insulating layer is on one side of the reflective layer away from the base substrate. The anode patterns are on one side of the insulating layer away from the base substrate, and each of orthographic projections of the anode patterns onto the base substrate at least partially overlaps the orthographic projection of the sub-pixel aperture area onto the base substrate. The light-emitting function layer is on one side of the anode patterns away from the base substrate. An orthographic projection of the light-emitting function layer onto the base substrate is within the orthographic projection of the sub-pixel aperture area onto the base substrate. The cathode is on one side of the light-emitting function layer away from the base substrate. An orthographic projection of the cathode onto the base substrate covers the orthographic projection of the light-emitting function layer onto the base substrate.
