Abstract:
An organic electroluminescent device includes a first electrode, an insulating layer, an organic light emitting layer, and a second electrode. The insulating layer is provided on the first electrode. The insulating layer includes a first opening for exposing a part of the first electrode. The organic light emitting layer includes a first part and a second part. The first part is provided on the part of the first electrode. The second part is provided on the insulating layer. The second electrode is provided on the organic light emitting layer. The second electrode includes a conductive part and a plurality of second openings. The conductive part is disposed on at least a part of the first part. Each of the second openings exposes a part of the organic light emitting layer. The second electrode is light-reflective.
