Abstract
The present disclosure provides a display substrate, a method for preparing the same, and a display device. The display substrate includes: a base substrate; a metal pattern located on the base substrate, and an anti-reflection pattern located on a surface of the metal pattern proximate to the base substrate, in which a difference between a first slope angle of the anti-reflection pattern and a second slope angle of the metal pattern is less than a first threshold, and a distance between a first edge of a side surface of the anti-reflection pattern proximate to the metal pattern and a second edge of a side surface of the metal pattern proximate to the anti-reflection pattern is less than a second threshold.
