Abstract: The present invention provides a barrier film laminate including a first barrier film that includes a first substrate layer and a first barrier layer formed on the first substrate layer, a second barrier film that includes a second substrate layer and a second barrier layer formed on the substrate layer, and an adhesive layer. In the barrier film laminate, the first barrier film is bonded with the second barrier film so that the first barrier layer faces the second barrier layer with the adhesive layer interposed therebetween. In one embodiment of the barrier film laminate, the adhesive layer is formed of an adhesive containing an epoxy resin, a curing agent having an amino group, and either a silane coupling agent having an epoxy group or a silane coupling agent having an amino group and two hydrolyzable functional groups.

Abstract: A phosphor protection film that includes two films that are bonded to each other via an adhesive layer. One of the two films is a film including an inorganic film layer. In the phosphor protection film, when the film including the inorganic film layer of the two films is a barrier film and the other film of the two films is a support film, the support film has a thickness occupying 72% or more of the total thickness of the phosphor protection film.
