A gas barrier film having both high gas barrier properties and heat resistance is provided. The above problem is solved by a gas barrier film in which a solvent-resistant layer, a cardo polymer layer, and a silicon oxynitride layer are formed in this order on both sides of a polyimide film. The solvent-resistant layer 3 is a layer for a solvent (for example, diglycol diether) contained in the cardo polymer layer-forming coating solution. As a preferred example, the solvent-resistant layer is made of an acrylic cured resin, and the cardo polymer layer Is made of an epoxy-based cured resin. [Selection] Figure 1 |
