Abstract: The present invention relates to a method for manufacturing a gas barrier film, including at least steps 1 to 3 (each step is as defined in the specification) in this order;



a gas barrier film including: a substrate; and a polysilazane-based compound-derived layer on at least one surface side of the substrate, wherein the polysilazane-based compound-derived layer satisfies a specific requirement; and
a gas barrier film including: a substrate; and a gas barrier layer laminate provided on at least one surface side of the substrate and including a gas barrier layer (XG) not adjacent to the substrate and a gas barrier layer (YG) located closer to the substrate than the layer (XG) and adjacent to the layer (XG), the gas barrier layers (XG) and (YG) being directly laminated, wherein the gas barrier layer laminate satisfies a specific requirement.

Abstract: To provide a gas barrier film having a high gas barrier property and a high modulus of surface elasticity and having excellent hygrothermal durability, a gas barrier film having less pinholes in the entire surface and having a high gas barrier property, and manufacturing methods of these. A first gas barrier film includes: a gas barrier layer containing silicon and oxygen, and a region in a thickness direction of the gas barrier layer, the region containing silicon, oxygen, and nitrogen, and having an element ratio of nitrogen of 5 at % or greater, and a thickness dM of the region being 30 nm or greater. A second gas barrier film includes a gas barrier layer containing silicon and oxygen, where, in a case where the gas barrier film having a predetermined size is sectioned into a predetermined number, a proportion of the number of sections having a water vapor transmission rate in a predetermined condition of less than 1.0×10−3 g/m2/day is not less than a predetermined proportion.
