Abstract

[Object] To provide a liquid crystal alignment layer that can easily be formed, to which an anchoring force can be efficiently induced with less polarized light for exposure, and that is effective in controlling the orientation and pretilt angle of liquid crystal molecules, and a compound and polymer that can be used for such a liquid crystal alignment layer. [Solution] A compound is represented by general formula (I): where
