Abstract:
A problem is, in a liquid crystal film in which an alignment layer and a liquid crystal composition layer having homogeneous alignment are formed on a support substrate, to improve adhesion between the alignment layer and the liquid crystal composition layer, and durability under a severe environment such as high temperature and high humidity. A solution is a non-liquid crystalline polymerizable compound having a radically polymerizable group and a cationically polymerizable group in a molecule is simultaneously used as an antistripping additive in a polymerizable liquid crystal composition layer having homogeneous alignment.
