摘要： An object of the present invention is to provide an organic EL light-emitting device in which a permeation and diffusion of moisture from outside are prevented and a stable light-emitting characteristic is able to be maintained for a long period. The present invention relates to an organic EL light-emitting device comprising a sealing layer, a hygroscopic layer and a protective layer, which are aligned on the back of an organic electroluminescence element under a predetermined condition, wherein the sealing layer and the protective layer are constituted from a specific material, whereby it is possible to maintain a stable light-emitting characteristic for a long period together with suppressing the deterioration caused by moisture being permeated from outside.
