Array substrate, manufacturing method thereof, and display apparatus

A method for manufacturing an array substrate, comprising:

• forming a pixel defining layer having a plurality of accommodating wells over a substrate, wherein a side wall of each of the plurality of accommodating wells comprises a hydrophilic side surface;
• and
• forming a hydrophobic material layer over the pixel defining layer, such that the hydrophilic side surface is partially covered by the hydrophobic material layer to thereby form an overlapped region having a hydrophobic outer surface and an exposed region having a hydrophilic outer surface, wherein the overlapped region is on a side of the exposed region distal to the substrate;
• wherein the forming a hydrophobic material layer over the pixel defining layer comprises:
• contacting the pixel defining layer with a hydrophobic material solution, such that a side thereof having openings of the plurality of accommodating wells is submerged in the hydrophobic material solution;
• and
• forming a layer of hydrophobic nanospheres in the hydrophobic material solution via self-assembly to thereby form the hydrophobic material layer over the pixel defining layer.

An array substrate, comprising:

• a substrate;
• a pixel defining layer having a plurality of accommodating wells over the substrate;
• and
• a hydrophobic material layer over the pixel defining layer;
• wherein:
• a side wall of each of the plurality of accommodating wells comprises a hydrophilic side surface, wherein:
• the hydrophilic side surface is partially covered by the hydrophobic material layer to thereby form an overlapped region having a hydrophobic outer surface and an exposed region having a hydrophilic outer surface, wherein the overlapped region is at a side of the exposed region distal to the substrate;
• the pixel defining layer comprises a hydrophilic material sub-layer and a hydrophobic material sub-layer, wherein:
• the hydrophobic material sub-layer is at a side of the hydrophilic material sub-layer distal to the substrate;
• the hydrophilic material sub-layer is exposed in each of the plurality of accommodating wells to thereby form the hydrophilic side surface in the side wall of the each of the plurality of accommodating wells.
