    摘要： The present invention provides a homeotropic alignment liquid crystal film comprising 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.

    摘要翻译： 本发明提供了一种垂直取向液晶膜，其包含液晶物质，该液晶物质含有具有氧杂环丁烷基的侧链液晶化合物作为构成，在取向基板上呈顺时针方向排列并且以垂直取向 通过使氧杂环丁烷基反应。 因此，可以稳定地制造垂直取向液晶膜，而不需要在惰性气体气氛下的光照射等复杂的步骤，并且在垂直取向和机械强度固定后的取向保持性优异。
