Abstract:
The present invention provides a liquid crystal film which comprises a liquid crystal layer having excellent retainability of homeotropic alignment and which has excellent interlayer adhesion between a cycloolefin polymer (COP) film and the liquid crystal layer. The liquid crystal film is produced by aligning homeotropically a liquid crystalline composition containing a (meth)acrylic compound having an oxetane group and fixing the composition in a homeotropic alignment by polymerizing the oxetane group directly on the COP film. The liquid crystal film is excellent in interlayer adhesion. The present invention also provides an optical element produced using the liquid crystal film.
