Abstract
An organic EL device includes: a first substrate having electrical conductivity; an organic layer formed on the first substrate; a second substrate having translucency; and an electrode layer formed on the second substrate. The electrode layer on the first substrate and the organic layer on the second substrate contact each other. The organic layer is not formed in the peripheral portion of the second substrate. In the region where the organic layer is not formed, a portion of the electrode layer is provided to extend, and the first substrate is not present to face the extended electrode layer, and the portion of the electrode layer is exposed to form an electrode portion. Thus, the electrode portion can be formed by a simple procedure in which, for example, the first substrate is removed, and the organic EL device can be efficiently manufactured.
