A photo-alignment layer having excellent long-termnstability to light and heat is manufactured by coating anmaterial for the photo-alignment layer, which contains andichroic dye having two or more polymerizable groups pernmolecule, on a substrate, and exposing the coating layer tonpolarized light, thereby imparting a photo-alignment function,nand polymerizing the polymerizable groups by heating or lightnexposure. |
