  To provide a photoalignable material that can yield a photoalignable film having a high optical uniformity and no alignment defect, and is excellent in sensitivity to allow photoalignment even with exposure in a short period of time, and a liquid crystal alignment film having a high alignment stability of a liquid crystal compound from the photoalignable material. A photoalignable polymer composition containing a specific photoalignable polymer and a specific polymer that is reactive with the photoalignable polymer is manufactured, and the photoalignable film is manufactured by applying the polymer composition onto a base material or the like, drying the applied composition thereon, and irradiating the dried composition with light. Furthermore, the liquid crystal alignment film is manufactured by allowing alignment of molecules of the liquid crystal compound in the photoalignment film.
