Abstract
An organic EL device including a stacked structure having an organic luminescent layer positioned between an anode and a cathode; and a sealing can having a desiccant-containing layer on its inner surface. The desiccant in the desiccant-containing layer provides an excellent long-term moisture resistance to the organic EL device, thereby generating no or a few dark spots thereon.
