Abstract: An organic electroluminescent display panel, its manufacturing method and a display device are disclosed. In the organic electroluminescent display panel, a pixel definition layer provided therein has opening regions corresponding to pixel areas in the OLED, and each of the opening regions has an opening larger than a bottom surface of the opening region (300). An upper surface (a) of the pixel definition layer is formed from a hydrophobic material, and an inclination surface (b) of the pixel definition layer corresponding to each of the opening regions is formed from a hydrophilic material. The above OLED can assure the uniformity of the film layers formed after the pixel definition layer can be guaranteed to improve the light emitting performance of the OLED.
