An organic EL device provided with a first film, a second film disposed facing the first film, and an organic EL element interposed between the first film and the second film. The second film is provided with a gas barrier layer containing a silicon atom, an oxygen atom, and a carbon atom. The silicon distribution curve, the oxygen distribution curve and the carbon distribution curve of the gas barrier layer satisfy the following conditions: (i) the ratio of the number of silicon atoms is the second largest in a region accounting for 90 % or more in the thickness direction of the gas barrier layer; (ii) the carbon distribution curve has at least one extreme value; and (iii) the difference between the maximum value and the minimum value of the ratio of the number of carbon atoms is 5 atom % or more in the carbon distribution curve. |
