Abstract
Provided is an organic EL device array in which water or oxygen hardly enters a light emitting region, and high-quality light emission can be maintained for a longer period of time. The organic EL device array includes: a light emitting region (region I) having a plurality of organic EL light emitting portions for emitting light in an organic compound layer disposed between a pair of electrodes; a protective layer in contact with an upper electrode of the pair of electrodes; a member disposed on the protective layer; an intermediate layer disposed between the protective layer and the member, in which a thinner portion of the intermediate layer is present outside a light emitting region (region O) within the surface thereof.
Claims9
An organic EL device array, which includes within a surface thereof a light emitting region having a plurality of organic EL light emitting portions for emitting light in an organic compound layer disposed between a pair of electrodes, comprising:
- a protective layer in contact with an upper electrode of the pair of electrodes;
- a member disposed on the protective layer;
- and
- an intermediate layer disposed between the protective layer and the member,
- wherein the intermediate layer has a thinnest portion outside the light emitting region within the surface of the organic EL device array.
