GAS BARRIER MEMBRANE, GAS BARRIER FILM USING SAME, ELECTRONIC DEVICE USING SAID GAS BARRIER MEMBRANE OR SAID GAS BARRIER FILM, AND PRODUCTION METHOD FOR GAS BARRIER MEMBRANE

摘要

The present invention provides a means with which a gas barrier membrane can satisfy both excellent bending properties and high water-vapor barrier properties in a high-temperature, high-humidity environment. The present invention relates to a gas barrier membrane having a region (a) that satisfies the following expression (1) and the following expression (2) when the composition is represented by M1M2_xN_y in the atomic composition distribution profile obtained when an XPS composition analysis is performed in the thickness direction. M1M2_xN_y Expression (1): 0.2 ≤ x ≤ 3.0 Expression (2): 0.6 ≤ y ≤ 1.4 x: Abundance ratio of transition metal M2 atoms with respect to non-transition metal M1 atoms y: Abundance ratio of nitrogen atoms with respect to non-transition metal M1 atoms
