ORGANIC ELECTROLUMINESCENT DEVICE, ILLUMINATION APPARATUS, AND ILLUMINATION SYSTEM

摘要

An organic electroluminescent device includes first and second substrates, first and second electrodes, an organic light emitting layer, and first and second terminal parts. The first substrate has an upper face including a device region and a periphery region surrounding the device region. The upper face is polygonal. The first electrode is provided on the device region. The organic light emitting layer is provided on the first electrode. The second electrode is provided on the organic light emitting layer. The second substrate is provided on the second electrode. The first terminal part is provided on the periphery region. The second terminal part is provided separated from the first terminal part on the periphery region. At least one of the first terminal part and the second terminal part extends along each of a plurality of sides of the upper face.
