An organic EL device having a drying medium capable of suppressing the growth
of a dark spot equipped with a water-capturing medium layer for chemically capturing
water placed on a water-capturing medium holding layer. The organic EL device is
comprised of a sealed container having a glass substrate and a sealing cap bonded
to the glass substrate. The sealed container is provided with a light emitting
region formed on the substrate which is formed of organic EL material layers placed
between a pair of opposite anode and cathode electrodes. The sealed container further
includes a water-capturing medium holding layer provided on an inner surface of
the container spaced apart from the light emitting region and a water-capturing
medium holding layer.
