Abstract:
The present invention provides a gas barrier laminated film including: a first barrier film having a first substrate, a first inorganic thin film layer, and a first gas barrier covering layer; and a second barrier film having a second substrate, a second inorganic thin film layer, and a second gas barrier covering layer; wherein the first barrier film and the second barrier film are laminated through an adhesive layer so that the first gas barrier covering layer and the second gas barrier covering layer are opposite to each other; the distance between the first inorganic thin film layer and the second inorganic thin film layer is about 1.0 μm or more; and the refractive index difference between the first gas barrier covering layer and the adhesive layer, and the refractive index difference between the second gas barrier covering layer and the adhesive layer are both about 0.05 or less.
