Abstract:
To provide a photoalignable material that can yield a photoalignable film having a high optical uniformity and no alignment defect, and allows photoalignment with exposure in a short period of time. A photoalignable polymer composition containing a specific photoalignable polymer having a silicone group or a fluorine-substituted alkyl group, and a photoalignable group, and a specific non-photoalignable polymer is manufactured, and the photoalignable film is manufactured by applying the polymer composition onto a base material or the like, drying an applied surface thereon, and irradiating the applied surface with light.
