ABSTRACT:
A film with alignment film which stably causes liquid crystal alignment and is excellent in adhesion between its constituting layers so as to give a high endurance and an excellent re-workability, and further to provide an optical device using the same. The film with alignment film contains at least a resin substrate and an alignment film, wherein the film is provided with a photocurable resin layer between the resin substrate and the alignment film, the photocurable resin layer being formed by use of a photo-cleaving type photopolymerization initiator. The optical device contains at least a resin substrate, an alignment film, and an optically functional layer, wherein the device is provided with a photocurable resin layer between the resin substrate and the alignment film, the photocurable resin layer being formed by use of a photo-cleaving type photopolymerization initiator.
