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.
在基底上涂覆一种用于光配位层的材料,其中包含一种每分子具有两个或两个以上可聚合基团的二色性
染料,然后将涂覆层暴露在偏振光下,从而赋予其光配位功能,并通过加热或光照射使可聚合基团聚合,从而制造出一种对光和热具有良好长期稳定性的光配位层。
