PROBLEM TO BE SOLVED: To provide an organic EL element maintaining stable light emitting property for long time, hardly generating cracks on a silicon compound, not damaging visibility of organic EL. SOLUTION: On the organic EL element composed of a pair of substrates of which at least one is transparent, a pair of electrodes interposed between the substrates, and an organic layer interposed between the pair of electrodes, a multi-layered sealing structure sealing the space between the substrate and a sealing base plate facing the substrate is arranged at outer peripheral part of the organic EL element. The multi-layered sealing structure has a buffer layer arranged at an outer peripheral layer of an organic sealing layer and the outer peripheral layer of the organic sealing layer and an elastic layer arranged on the silicon compound layer arranged at the outer peripheral part of the buffer layer and the silicon compound layer. The coefficient of linear expansion of the buffer layer is smaller than that of the organic sealing layer and larger than that of the silicon compound layer, and the coefficient of linear expansion of the elastic layer is smaller than that of the silicon compound layer.
