Organic light-emitting diode display substrate, manufacturing method thereof and display device
The present disclosure provides in some embodiments a method for manufacturing an OLED display substrate, including a step of forming a PS on a substrate with an anode and a step of forming a pattern of a pixel definition layer. The step of forming the PS is performed no later than the step of forming the pattern of the pixel definition layer. According to the present disclosure, the PS is able to be formed prior to the formation of the pattern of the pixel definition layer, or the PS and the pattern of the pixel definition layer are formed simultaneously through one single patterning process.
