The invention discloses an electroluminescent display panel and a manufacturing method thereof, and a display device. The electroluminescent display panel includes a base substrate and a transparent cover disposed opposite to the base substrate, wherein a pixel definition layer is disposed on a side of the base substrate facing the transparent cover, the pixel definition layer defines multiple opening regions arranged in an array, one opening region corresponds to one sub pixel, a cathode and a protective layer are sequentially disposed on a side of the pixel definition layer and the opening region away from the base substrate, the protective layer includes a transparent non-conductive region and a conductive region, the transparent non-conductive region covers the opening regions, the conductive region is doped with a conductive material, the conductive region is within the coverage range of the pixel definition layer, a transparent conductive layer is disposed on a side surface of the transparent cover adja
