Abstract

An organic light emitting diode display panel, a manufacturing method thereof and a display device are disclosed, for reducing the number of inkjet heads used in inkjet printing or alleviating the swath mura at printing interfaces. The method comprises manufacturing an anode layer, a light emitting layer and a cathode layer on a base substrate, and the method can further comprise manufacturing by an entire-surface coating process a function layer having a first preset thickness between the anode layer and the light emitting layer; and in a first preset region of the function layer that has been manufactured, manufacturing by an inkjet printing process a function layer having a second preset thickness.
