Abstract
The present invention provides a film for use in organic EL device, having a sufficient gas-barrier property for protection of organic EL device, and an organic EL device structure using such a film. That is, the present invention provides a film for use in organic EL device, made of an organic inorganic hybrid material whose molecules have an organic skeletal moiety and an inorganic skeletal moiety and contain fluorine group and siloxane group.
Claims12
A film for use in organic EL device, made of an organic inorganic hybrid material whose molecules have an organic skeletal moiety and an inorganic skeletal moiety and comprises a fluorine group and a siloxane group, wherein the main skeleton of each molecule contains a siloxane group-bonded polychloroethylene.
A film used for encapsulating an organic EL device, comprising a polyethylene terephthalate substrate, an organic inorganic hybrid material film formed on one side of the substrate, and a vapor-deposited inorganic material film formed on the surface of the organic inorganic hybrid material film.
A film used for sealing of organic EL device, comprising two three-layered films and an adhesive layer interposed between the two three-layered films, wherein each of the two three-layered films comprises a polyethylene terephthalate substrate, an organic inorganic hybrid material film formed on one side of the polyethylene terephthalate substrate and a vapor-deposited inorganic material film formed on the surface of the organic inorganic hybrid material film and wherein the upper side of the adhesive layer is in contact with the other side of the polyethylene terephthalate substrate of one of the two three-layered films and the lower side of the adhesive layer is in contact with the vapor-deposited inorganic material film of the other three-layered film.
