Claim Text:
1. An organic EL device comprising: a first substrate having electrical conductivity; an organic light emitting layer provided on the first substrate; a second substrate having translucency; and an electrode layer provided on the second substrate, wherein a first surface of the first substrate, on which the organic light emitting layer is provided, and a surface of the second substrate, on which the electrode layer is provided, are located so as to face each other, and the organic light emitting layer is not present in a region of a peripheral portion of the first substrate, on the second substrate, a portion of the electrode layer is provided in a portion facing the region of the peripheral portion of the first substrate where the organic light emitting layer is not present, so as to define an extended portion that extends to an outer peripheral side of a region where the organic light emitting layer is present, the first substrate is not present in a portion facing the extended portion of the electrode layer, and at least a part of the extended portion of the electrode layer is exposed from the first substrate, thereby constituting an electrode taking-out portion, one surface of the extended portion of the electrode layer that is exposed from the first substrate physically contacts the second substrate, the one surface being opposite a surface of the electrode layer, that faces the first substrate, the first substrate, on which the organic light emitting layer is provided, and the second substrate, on which the electrode layer is provided, are joined to each other by an adhesive layer provided on a peripheral portion of one of the first substrate and the second substrate, the first substrate defining an electrode other than the electrode layer, at least a portion of a second surface of the first substrate is exposed to an exterior of the organic EL device, the second surface of the first substrate being opposite the first surface of the first substrate, the electrode layer extends continuously along an extending direction of the first substrate from a first outer edge of the first substrate to a second outer edge of the first substrate, the first outer edge of the first substrate and the second outer edge of the first substrate each overlap with the electrode layer in a cross-sectional direction of the organic EL device.
