Abstract

The invention discloses a pixel demarcation layer and a manufacturing method thereof and a display substrate, belongs to the technical field of display. The manufacturing method of the pixel demarcation layer includes providing a substrate substrate; Forming a precursor solution layer on the substrate, wherein the precursor solution layer is made of a precursor solution, and the precursor solutionis formed by mixing a hydrophobic organic material and a hydrophilic inorganic magnetic material; Applying a magnetic field to a substrate on which the precursor solution layer is formed to obtain ahydrophilic material layer formed of the inorganic magnetic material and a hydrophobic material layer formed of the organic material; The liquid-repellent material layer and the liquid-repellent material layer are patterned to obtain a liquid-repellent material pattern and a liquid-repellent material pattern stacked in a direction away from the substrate. The invention simplifies the preparation process of the pixel bounding layer, improves the production efficiency of the pixel bounding layer, and improves the structural stability of the pixel bounding layer. The present invention is used tofabricate a pixel bounding layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel defining layer, a manufacturing method thereof, and a display substrate. Background technique [0002] A self-illuminating display panel generally includes a base substrate and an anode, a light-emitting layer, a cathode, and the like disposed on the base substrate in sequence. Wherein, the light emitting layer generally includes a hole injection layer, a hole transport layer, a light emitting material layer, an electron transport layer and an electron injection layer. Each film layer in the light-emitting layer can be prepared by ink-jet printing (Ink-Jet Printing, IJP) technology. Before using the inkjet printing technology to prepare the light-emitting layer, it is necessary to form a pixel defining layer on the base substrate, and then sequentially spray the corresponding solution onto the base substrate on which the pixel defining layer is formed, so as to form eac...
