Document Type and Number:
WIPO Patent Application WO/2020/258462
Kind Code:
A1
Abstract:
A display panel, comprising a substrate (1), a pixel definition layer (2) and nano-columnar structures (3) on the pixel definition layer. The preparation method for the display panel comprises a provision step, a coating step, a drying step, a baking step, a temperature reduction step, an exposure step, a development step, a high-temperature curing step, and a dry-etching step. By means of using carbon tetrafluoride in a mixed gas of argon to dry-etch the pixel definition layer (2), nano-columnar structures (3) are formed on the surface of the pixel definition layer (2), such that the roughness of the surface of the pixel definition layer is increased, and the hydrophobicity of the surface of the pixel definition layer is enhanced.
