Abstract: A pixel define layer and manufacturing method thereof and the related light emitting display are disclosed. The pixel define layer is arranged on a conductive layer of a substrate and comprises a base film layer. The base film layer has a plurality of openings each of which corresponds to a light-emitting region of a sub-pixel unit. A spacing base body is formed between the adjacent openings. An upper surface of each spacing base body is coated with a hydrophobic quantum dot material and a side wall of each opening is coated with a hydrophilic quantum dot material. With the pixel define layer and manufacturing method thereof and the related light emitting display according to embodiments of the disclosure, the ink within the sub-pixel would not ooze to the outside of the sub-pixel to result in color mixture between the adjacent sub-pixels, and the light emitting region within the pixel would not be decreased. By selecting suitable quantum dot materials, the photochromic efficiency can be improved.

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.
