Abstract
The invention relates to a desiccant suitable for being used with an organic EL element having a solid sealing structure. The desiccant is provided for suppressing any effect on an organic layer, and guaranteeing flowability while being filled. An organic EL element has a container, which includes an element substrate on which a laminate of a pair of electrodes and an organic layer located between the pair of electrodes is disposed, a sealing substrate spaced apart from the element substrate, a sealing agent disposed between the element substrate and the sealing substrate thereby hermetically sealing the container, and the desiccant disposed inside the container. In this configuration, the container is filled with the desiccant, and the laminate is thus surrounded by the desiccant. The desiccant is obtained by mixing a water-trapping agent with silicone. The water-trapping agent is present in an amount of 50-95% by weight and the silicone is present in an amount of 5-50% by weight based on the total weight of the desiccant.
