Abstract:
1. A gas barrier film comprising a gas barrier laminate on a substrate film, in which the gas barrier laminate comprises at least one three-layer unit consisting of a first silicon oxynitride layer, a silicon oxide layer directly on the first silicon oxynitride layer, and a second silicon oxynitride layer directly on the silicon oxide layer, wherein: at least one of the silicon oxynitride layers has a refractive index of from 1.7 to 2.1; at least one of the silicon oxynitride layers comprise 98 mass % or more of silicon oxygen and nitrogen combined; the silicon oxide layer comprises 98 mass % or more of silicon and oxygen combined; at least one of the silicon oxynitride layers is represented by formula SiO the ratio of silicon and oxygen in the silicon oxide layer is from 1:1.8 to 1:2.0.
