Title:
METHOD FOR MANUFACTURING DISPLAY SUBSTRATE, DISPLAY SUBSTRATE, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/155495
Kind Code:
A1
Abstract:
The present disclosure relates to a method of preparing a display substrate. The method may include forming a pattern layer on a base substrate; forming a planarization layer on the pattern layer, the planarization layer comprising a host material and a hydrophilic material and a hydrophobic material mixed in the host material; treating the planarization layer so that the host material reacts with the hydrophilic material to form a hydrophilic polymer, the host material reacts with the hydrophobic material to form a hydrophobic polymer, and the planarization layer is delaminated to form a first sub-planarization layer and a second sub-planarization layer; and cleaning the planarization layer with a cleaning solution that reacts with the hydrophobic polymer to remove at least part of the first sub-planarization layer. The first sub-planarization layer includes the hydrophobic polymer, and the second sub-planarization layer includes the hydrophilic polymer.
