[Problem] To provide a cured-film-forming composition for providing an alignment material that has superior vertical alignment properties and adhesiveness, and is capable of vertically aligning polymerizable liquid crystals with high sensitivity even upon a resin film, and for providing a phase difference material that uses such an alignment material. [Solution] A cured-film-forming composition comprising: (A) a low molecular compound having groups with vertical alignment properties and functional groups capable of thermal crosslinking; and (B) a cross-linking agent. An alignment material, characterized by being obtained using said composition. A phase difference material, characterized by being obtained using said composition.
