Abstract: The present disclosure provides an organic light-emitting diode, a display panel and a display device, relating to the field of display technologies. The organic light-emitting diode includes a first electrode, at least two emission layers, an optical modulation layer, and a second electrode. A thickness of the optical modulation layer has a relatively bigger range. Therefore, in the case that the thicknesses of other film layers between the first electrode and the second electrode vary, an optical modulation layer having a different thickness can be provided to adjust the microcavity length of the organic light-emitting diode, thereby ensuring the optical performance of the organic light-emitting diode and the display effect of the display panel.
