Abstract
It is an object of the present invention to provide a gas barrier film improved in gas barrier characteristics by decreasing the adsorbent of the surface of a gas barrier layer to water and the like. The present invention attains the above object by providing a gas barrier film comprising a substrate, a gas barrier layer which is a vacuum deposition film, formed on one surface or both surfaces of the above substrate, and a water-repellent layer which is a film having water repellency, formed on the above gas barrier layer.
Claims28
A gas barrier film comprising a substrate, a gas barrier layer which is a transparent layer formed of an inorganic oxide, formed on one surface or both surfaces of the substrate, and a water-repellent layer which is a film having water repellency, formed directly on the gas barrier layer on the side of said gas barrier layer opposite the substrate,
- wherein the gas barrier film further comprises a water-repellent layer which is a film having water repellency, formed between the substrate and the gas barrier layer.
A gas barrier film comprising a substrate, a gas barrier layer which is a transparent layer formed of an inorganic oxide, formed on one surface or both surfaces of the substrate, and a water-repellent layer which is a film having water repellency, formed directly on the gas barrier layer,
- wherein the water-repellent layer is a layer formed by a vacuum deposition method, and
- the film thickness of the water-repellent layer is in a range from 1 nm to 1000 nm.
