Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an organic electroluminescent film substrate of low cost, which includes a gas barrier layer having high gas barrier property and which has an improved light-extraction function; and provide an organic electroluminescent device using an organic electroluminescent resin film substrate.SOLUTION: In an organic electroluminescent film substrate at least having on a resin film 1, a first gas barrier layer 3, a stress moderation layer 4 and a second gas barrier layer 3 from a lower layer side, the second gas barrier layer is a ceramic layer and the stress moderation layer is a layer having a function of diffracting or scattering light beams. 【課題】高いガスバリア性を有するガスバリア層を備えると共に光取り出し機能が向上した低コストの有機エレクトロルミネッセンス用フィルム基板と、有機エレクトロルミネッセンス用樹脂フィルム基板を用いた有機エレクトロルミネッセンスデバイスを提供する。【解決手段】樹脂フィルム１上に、下層側から少なくとも第１ガスバリア層３、応力緩和層４、第２ガスバリア層３を有する有機エレクトロルミネッセンス用フィルム基板において、第２ガスバリア層はセラミック層であり、応力緩和層は、光を回折もしくは散乱させる機能を有する層である構成とする。【選択図】図６
