Abstract
An organic EL device has a structure in which an anode, a hole transporting layer, an organic luminescent layer, and a cathode are disposed on a glass substrate in this order. The organic EL device further has a protective layer covering an outer surface of the structure to protect it from an external environment. The protective layer is formed by an ALE method at a temperature lower than glass transition temperatures materials constituting the hole transporting layer and the organic luminescent layer.
