Abstract
Provided are a display panel and a method for preparing same and a display device. The preparation method includes: forming a step-shaped opening on a pixel define film using a patterning process; forming an organic photoresist in the opening; performing fluorinated plasma treatment on the pixel define film outside the opening such that the pixel define film outside the opening forms a first pixel define layer having a hydrophilic surface layer, and the remaining pixel define film forms a hydrophobic second pixel define layer; and removing the organic photoresist in the opening.
