PROBLEM TO BE SOLVED: To provide a safe organic light emission element enabled to keep stable light emission for long time. SOLUTION: An organic light emission laminated body, at least having a layer containing one or a plurality of organic compound between a positive electrode and a negative electrode, is housed in an airtight container and isolated from the outside air. A compound expressed by a formula; R-NCO, is used as a desiccating agent, where, R represents substitutional or non- substitutional alkenyl group, substitutional or non-substitutional allyl group, substitutional or non-substitutional styryl group, substitutional or non- substitutional acryl group, or alkenyl substituted heterocyclic group. |
