METHOD FOR MANUFACTURING PIXEL DEFINING LAYER, METHOD FOR MANUFACTURING OLED, PIXEL DEFINING ELEMENT, OLED, AND DISPLAY DEVICE

摘要

Disclosed are a method for manufacturing a pixel defining layer, a method for manufacturing an OLED, a pixel defining element, an OLED, and a display device. The method for manufacturing a pixel defining layer comprises: providing a substrate; forming a first defining pattern on the substrate, the first defining pattern being formed by a recessed receiving groove, and the recessed receiving groove being formed by performing inkjet printing using a first material to form a first defining pattern layer in a predetermined region of the substrate and drying the first defining pattern layer; and forming a second defining pattern in the recessed receiving groove, the second defining pattern being formed by performing inkjet printing using a second material, and the first defining pattern and the second defining pattern forming a pixel defining layer.
