Abstract
A method for manufacturing an alignment layer is provided. An alignment material having an ultraviolet reactive functional group is formed on a substrate. A pre-baking process is performed on the alignment material located on the substrate. An ultraviolet polarizer is provided on the substrate. An aligning process is performed on the pre-baked alignment material, so as to irradiate an ultraviolet light to the substrate. The ultraviolet light passes through the ultraviolet polarizer and irradiates to the pre-baked alignment material. A post-baking process is performed on the alignment material after being aligned, so as to fully cure the alignment material.
