1. A method for manufacturing an alignment layer, comprising:
providing a substrate;
forming an auxiliary layer on the substrate;
spraying an alignment material solution on the auxiliary layer through inkjet printing, wherein the alignment material solution includes an alignment material and a first solvent, and the auxiliary layer has the same polarity as the first solvent; and
performing a curing process for curing the alignment material solution, so as to form an alignment layer.
