  • Patent number: 11829034
    Abstract: An encapsulant sheet suitable for encapsulating a light-emitting element in, for example, a self-luminous display or for direct backlights. The encapsulant sheet is a single-layer or multi-layer resin sheet that includes an adhesive layer exposed at a topmost surface. The Vicat softening point is greater than 60° C. and no higher than 100° C. The melt viscosity of the encapsulant sheet, at a shear velocity of 2.43×10 sec?1 and measured at a temperature of 120° C. is at least 5.0×104 poise and no more than 1.0×105 poise. The adhesive layer contains a polyolefin and a silane component, and a content of the silane component relative to the resin component of the adhesive layer is at least 0.03% by mass and less than 10% by mass.

  • Patent number: 7192625
    Abstract: In manufacturing a barrier-forming film, a vapor-deposited inorganic oxide film is provided on a face of a substrate film. An annealing treatment is applied to the substrate film having said vapor-deposited inorganic film. The substrate film is a resinous film which selected from a group consisting of polyesters, polyamides and polypropylenes. The annealing treatment includes a heating treatment carried out at a temperature within the range from 55° C. to 150° C. in order to cause thermal shrinkage of the substrate film and to increase density of the vapor-deposited inorganic oxide film. The vapor-deposited inorganic oxide film includes a vapor-deposited silicon oxide film or a vapor-deposited aluminum oxide film.
