ABSTRACT:
A homeotropic alignment liquid crystal film is provided with a liquid crystalline substance containing a side chain liquid crystalline compound having an oxetanyl group, as a constituent, aligned homeotropically on an alignment substrate while being in a liquid crystal state and fixed in the homeotropic alignment by allowing the oxetanyl group to react. Thus, the homeotropic alignment liquid crystal film can be stably produced without necessitating a complicated step such as light irradiation under an inert gas atmosphere and is excellent in alignment retainability after being fixed in the homeotropic alignment and in mechanical strength.
