Abstract

A display substrate, a method for manufacturing the same, and a display device are provided. The display substrate includes a base substrate, a black matrix pattern on the base substrate, display units respectively in regions defined by the black matrix pattern, and a light-reflecting wall between at least two adjacent display units, where at least one of the at least two adjacent display units is a quantum dot display unit, and a reflectance of the light-reflecting wall to light in a first wavelength range is greater than a preset threshold.
