摘要： A method for manufacturing an array substrate includes: forming a pixel defining layer having a plurality of accommodating wells over a substrate, and forming a hydrophobic material layer over the pixel defining layer. A side wall of each accommodating well comprises a hydrophilic side surface. 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. The overlapped region is on a side of the exposed region distal to the substrate. The array substrate manufactured thereby allows an organic functional layer to be evenly fabricated in each accommodating well of the pixel defining layer via inkjet printing.
