ABSTRACT:
A hologram member and a method of preparing a volume type phase hologram film includes forming a volume type phase hologram in a polymer film formed on a substrate and comprised of a vinylcarbazole polymer, separating the polymer film from the substrate and allowing the hologram to be supported on the substrate so that the surface of the hologram not having contacted the substrate, contacts the substrate.
