An organic EL device includes a first substrate and a plurality of organic EL elements above a first portion of the first substrate. A first inorganic layer covers the plurality of organic EL elements. An active layer is above a second portion of the first substrate that is different than the first portion. The active layer comprises a material that is at least one of hygroscopic and oxidizable. A second inorganic layer covers the active layer. A second substrate is opposite the first substrate, with the plurality of organic EL elements being between the first and second substrates. A seal extends between the first and second substrates to define a sealed space between the first and second substrates. The second inorganic layer includes through-holes that expose the active layer to the sealed space that is defined by the first substrate, the second substrate, and the seal.
