Abstract:
1. An organic light emitting device, comprising: a first substrate; a thin film structure disposed on the first substrate; a second substrate facing the first substrate; an adhesive disposed between the first substrate and the second substrate to enclose and seal a region comprising the thin film structure; a dehumidification buffer layer of a sheet type disposed between the thin film structure and the second substrate, the dehumidification buffer layer being enclosed by the adhesive; and a partition enclosing the thin film structure, the dehumidification buffer layer being disposed inside a region defined by the adhesive, wherein: the dehumidification buffer layer comprises a mixture of an ionomer and aluminum (Al); the dehumidification buffer layer is adhered on an inside surface of the second substrate, and there is empty space between the dehumidification buffer layer and the thin film structure; the adhesive comprises a hardening frit; the partition comprises an epoxy resin; and the dehumidification buffer layer contacts the partition.
