The disclosure discloses an organic electroluminescent display panel, a method for manufacturing the same, and a display device, where organic light-emitting layers of display sub-pixels and virtual sub-pixels may be created on an underlying substrate through evaporation using a fine metal mask and a shielding mask arranged in a stack, and the area of the organic light-emitting layer of a non-rectangular shaped virtual sub-pixel among the virtual sub-pixels is smaller than the area of the organic light-emitting layer of a display sub-pixel capable of emitting light in the same color.
