Problems solved by technology
The invention provides a method for processing a photoalignment layer in an appropriate relative humidity range. A photoalignment material that is used is a noncomposite azo dye, photopolymerized azodye compound material or thermopolymerized azo dye compound material, so that the photoalignment material uniformly covers a substrate, and is subjected to exposure to provide consistent alignment, and light is linearly polarized light. The quality of the photoalignment layer obtained by photoalignment under relative humidity is good.
