Abstract: A top-emitting organic electroluminescent display panel, a manufacturing method, and a display device. The top-emitting organic electroluminescent display panel comprises: a substrate, a layer of white organic light emitting diodes and a thin film encapsulation layer arranged on the substrate in sequence. The thin film encapsulation layer comprises at least two inorganic thin film layers and at least one organic thin film layer. At least one organic thin film layer is a color filter layer, the color filter layer being arranged between the at least two inorganic thin film layers. Since one of the organic thin film layers in the thin film encapsulation layer is a color filter layer, the color filter layer does not have to be arranged above the thin film encapsulation layer separately, thus reducing the number of film layers, simplifying the film layer structure, reducing manufacturing costs, and improving the luminous efficiency and the display effect.
