Abstract

An organic electroluminescence display panel a manufacturing method thereof, and a display device are described. Each sub-pixel in the display panel includes a first electrode layer and a second electrode layer that are arranged oppositely, and an organic light-emitting function layer, and at least one of the sub-pixels further includes a light-absorbing layer disposed on a side of the second electrode layer away from the organic light emitting function layer. The light-absorbing layer absorbs the wavelength band where the tailing peak of the emission spectrum curve is located.
