ABSTRACT:
The present invention provides a liquid crystal aligning agent which provides a liquid crystal alignment film having surface anchoring force and pretilt angle development stability by an optical aligning method. The liquid crystal aligning agent comprises a polymer having a photo-crosslinkable structure a structure having at least one group selected from the group consisting of a fluorine-containing organic group, an alkyl group having 10 to 30 carbon atoms and alicyclic organic group having 10 to 30 carbon atoms and optionally, (C) a thermally crosslinkable structure.
