摘要：
The present disclosure provides a method for manufacturing an OLED display substrate, including a step of forming a pattern of a pixel definition layer on a substrate through a patterning process. A bottom wall of the pixel definition layer is formed on the substrate, a top wall of the pixel definition layer is arranged parallel to the bottom wall, and a side wall of the pixel definition layer is angled relative to the top wall at an acute angle.
