Claim Text:
1. A gas barrier film comprising: a substrate; at least three organic layers; and at least two inorganic layers, wherein said at least three organic layers include a first organic layer directly formed on said substrate, a second organic layer which is an uppermost layer farthest from said substrate, and one or more intermediate organic layers between said first organic layer and said second organic layer, each intermediate organic layer being sandwiched between two inorganic layers, wherein each of said at least three organic layers and each of said at least two inorganic layers are alternatively laminated on said substrate in such a way that one of an organic layer and an inorganic layer is formed on the other of the organic layer and the inorganic layer, wherein said first organic layer is thicker than said one or more intermediate organic layers, and said second organic layer is thinner than said one or more intermediate organic layers, wherein said second organic layer is thicker than a thickest inorganic layer of said at least two inorganic layers, wherein a highest refractive index among each of said at least three organic layers is lower than a lowest refractive index among each of said at least two inorganic layers, wherein a refractive index of said second organic layer is lowest in refractive indices of each of said at least three organic layers, wherein the refractive index of said second organic layer ranges from 1.35 to 1.55, and refractive indices of each of said one or more immediate organic layers range from 1.45 to 1.72, wherein refractive indices of each of said at least two inorganic layers is 1.82 or less, and wherein a total light transmittance of the gas barrier film is equal to or larger than 85%.
