ORGANIC ELECTROLUMINESCENT DEVICE AND LIGHTING APPARATUS

摘要

According to one embodiment, an organic electroluminescent device includes a first electrode, a plurality of second electrodes and an organic light-emitting layer. The first electrode includes a first major surface and is optical transparency. The second electrodes extend in a first direction parallel to the first major surface and are separated from each other in a second direction parallel to the first major surface and perpendicular to the first direction. An optical transmittance of the second electrodes is lower than an optical transmittance of the first electrode. A distance along the second direction between a line extending in the first direction and a side surface of each of the second electrodes continuously increases and decreases along the first direction. The side surface is unparallel to the first major surface. The organic light-emitting layer is provided between the first electrode and the second electrodes.
