An organic EL display device (1), which is provided with a TFT substrate (a substrate) (2) and an organic EL element (an electroluminescent element) (4) that is provided on the TFT substrate (2), is provided with a sealing film (14) for sealing the organic EL element (4). This sealing film (14) is configured of a multilayer structure that is composed of an organic layer (14b) and inorganic layers (14a, 14c). The carbon content rate in a peripheral portion (14b2) of the organic layer (14b) is set to be lower than the carbon content rate in a central portion (14b1) of the organic layer (14b).
