HOMEOTROPIC ALIGNMENT LAYER, LIQUID CRYSTAL ALIGNMENT LAYER AND ITS MANUFACTURING METHOD, OPTICAL FILM, AND IMAGE DISPLAY APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a homeotropic alignment layer which keeps a homeotropic aligning property and has an excellent adhesion property to a substrate and a liquid crystal alignment layer.

SOLUTION: The homeotropic alignment layer is made of a crosslinked product of a block polymer composition which contains: a block structural unit comprising a monomer unit of alkyl (meth)acrylate (1) having a 1-10C alkyl group; and a block structural unit comprising a monomer unit of alkyl (meth)acrylate (2) having a 12-28C alkyl group.
