Provided are a gas barrier film that is simply and economically manufactured, and has high hardness and strength, excellent gas blocking properties, controllable refraction index and transparency, and a compositionally gradient structure, and a method of producing the same. The gas barrier film includes a base material; and an organic/inorganic hybrid gas barrier layer that is formed on the base material and has a composition-gradient structure. The organic/inorganic hybrid gas barrier layer has a network structure having—O—Si—O—linkages. The network structure contains an organic functional group having a carbon atom directly linked to a silicon atom of the—O—Si—O—linkages, and other element that exists in an oxide form in the interstitial location of the network structure or that is linked to an oxygen atom of the—O—Si—O—linkages, wherein the other element comprises at least one selected from alkali metal, alkaline earth metal, transition metal, post transition metal, metalloid, boron, and phosphorous. |
