Abstract: The present disclosure relates to the field of display technology and provides an organic light emitting diode, an OLED display substrate and a display device. It can solve the problem of low continuity in inkjet printing and complicated computer programs between different materials of light emitting layers in the existing organic light emitting diodes. The organic light emitting diode includes a cathode, an anode, and a functional layer between the cathode and the anode; wherein the functional layer includes a first light emitting layer and a second light emitting layer disposed in sequence in a direction away from the anode; the first light emitting layer comprises a first material emitting blue light; and the first light emitting layer and the second light emitting layer form an aggregate in excited state for emitting light of a color different from blue after the cathode and the anode are connected.
