A lamination film for an electronic device, having excellent gas-barrier properties (e.g., barrier properties against water vapor), is provided.
A lamination film 20 comprises, in sequence: a base film 25 comprising a transparent polymer; an anchor layer 24 formed on a first side of the base film, the anchor layer comprising a cured product of a polymerizable composition containing a vinyl monomer and/or prepolymer; a barrier layer 23 comprising a metal or a metal compound; an etching protection layer 22 having an acid resistance or an alkali resistance; and a transparent electroconductive layer 21 comprising an inorganic compound. The vinyl monomer and/or prepolymer contains at least a silicone (meth)acrylate monomer and/or prepolymer. The lamination film 20 may comprise an anti-glare layer 26 formed on a second side of the base film. The lamination film 20 is disposed at a display side with respect to an ink layer of an electronic paper.
