摘要： The disclosure discloses an electroluminescent display panel, a method for fabricating the same, and a display device. Where the electroluminescent display panel includes: a base substrate; a pixel definition layer located on the base substrate and including a plurality of opening regions for defining sub-pixel light-emitting areas; and light-emitting function layers, which cover the plurality of opening regions in a one-to-one correspondence manner, of sub-pixels; where the plurality of opening regions include normally-shaped opening regions and abnormally-shaped opening regions at an edge of an abnormally-shaped display area; and an area of each of the abnormally-shaped opening regions is smaller than an area of a normally-shaped opening region for defining a sub-pixel having a same light-emitting color.
