ABSTRACT:
A photo-alignment material useful in liquid crystal alignment films comprises a maleimide-based repeating unit, or a maleimide-based repeating unit and at least one additional repeating unit. The photo-alignment materials of the invention may be used in liquid crystal display devices to improve the electrical and electrooptical properties of the alignment film, and thereby improve the reliability of products using the alignment films.
