Method of manufacturing photo-alignment layer

A photo-alignment layer having excellent long-term stability to light and heat is manufactured by coating a material for the photo-alignment layer, which contains a dichroic dye having two or more polymerizable groups per molecule, on a substrate, and exposing the coating layer to polarized light, t...

Summary:A photo-alignment layer having excellent long-term stability to light and heat is manufactured by coating a material for the photo-alignment layer, which contains a dichroic dye having two or more polymerizable groups per molecule, on a substrate, and exposing the coating layer to polarized light, thereby imparting a photo-alignment function, and polymerizing the polymerizable groups by heating or light exposure.
