Abstract
There is provided a gas barrier clear filmas a polymer substrate that is flexible, is light, is free from cracking, can be bent, has a high level of heat resistance, is excellent particularly in gas shielding properties, and can be used as an alternative to glass substrates. The gas barrier clear film comprises: a clear resin base material filmhaving a coefficient of linear expansion of 15 to 100 ppm/K and a glass transition temperature Tg of 150 to 300° C.; and a first clear inorganic compound layerA, a sol-gel coat layerA, and a second clear inorganic compound layerB provided in that order on the clear resin base material film. The second clear inorganic compound layerB has an Ra (average roughness) value of not more than 5 nm and an Rmax (maximum roughness) value of not more than 80 nm.
