Abstract
A novel dioxetane compound is provided having a cationically polymerizable oxetane group, which compound is excellent in compatibility with a liquid crystalline compound and a non-liquid crystalline compound. An optical film is also provided with excellent liquid crystal orientation retention properties and mechanical strength, produced by aligning a composition of the dioxetane compound and a cationically polymerizable compound in a liquid crystal orientation and fixing the liquid crystal orientation by polymerization. Further, a liquid crystal display device is provided with the optical film.
