[Problem] To provide: an alignment member that has excellent alignment sensitivity and alignment uniformity, is resistant to a solvent in a liquid crystal solution even when the alignment member is a thin film, and can function as a protection layer for protecting a film substrate; and a cured film formation composition for obtaining the alignment member. [Solution] This cured film formation composition contains (A) a compound having a photoalignable group and a substituent selected from the group consisting of a hydroxy group, a carboxyl group, and an amino group, (B) a polymer obtained by polymerization of monomers including at least an N-alkoxymethyl (meth)acrylamide compound, and (C) a polymer obtained by polymerization of monomers including at least an N-hydroxyalkyl (meth)acrylamide compound, and optionally further contains a crosslinking catalyst as a component (D) and an adhesion-improving component as a component (E). This cured film formation composition is used to form a cured film, and a photoalignment technique is utilized to form an alignment member. A polymerizable liquid crystal is applied to the alignment member and then cured to obtain a retardation member.
