Summary:PROBLEM TO BE SOLVED: To provide an organic EL display device in which a large amount of moisture absorbent is formed in a limited narrow region and in which the stability of characteristics of an organic EL element is realized. SOLUTION: The device is equipped with a rectangular element substrate, having a display region in which a plurality of light-emitting elements are arranged, and a sealing substrate fixed and adhered to the element substrate via a sealing material in a jetty formed at a periphery edge opposed to the element substrate. The moisture absorbent, formed in a region which is in a recessed face, surrounded by the jetty of the sealing substrate and which is not overlapped with the display region, contains a moisture absorbent comprising a set of a plurality of linear patterns which are connected to neighboring other moisture absorbents and arranged in parallel, and the cross-sectional shape of the direction crossing its longitudinal direction has a plurality of mutually continuous ranges of mounds.
