    Abstract: The present invention relates to a photoalignment layer, for example, a liquid crystal alignment layer, which is able to realize the wide viewing angle and contrast ratio characteristics of a photopolymerizable alignment layer, and to facilitate interaction with the liquid crystal layer, thereby improving alignment stability and reducing image sticking, and a liquid crystal cell including the same. The liquid crystal alignment layer includes a photo-alignment layer including a photo-alignment polymer having at least partially photo-aligned photoreactive groups; and a mesogen layer including a cured product of a reactive mesogen that is liquid crystal-aligned by the photo-aligned photoreactive group, in which the photo-alignment polymer include a norbornene-based polymer having a particular structure.
