Abstract: Provided in the present disclosure are a display panel and a manufacturing method therefor, and a display apparatus. A pixel defining layer includes a plurality of first barrier walls and a plurality of second barrier walls, which are arranged in an intersecting manner, where a height of the first barrier wall is smaller than a height of the second barrier wall, and orthographic projections of via holes for connecting light emitting devices on a base substrate are located in orthographic projections of the second barrier walls on the base substrate. Due to a great thickness of the second barrier walls, an effect of covering via holes can be better by providing the via holes below the second barrier walls.

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.
