Patent ID: 7982392

Claim:
An organic electroluminescent display device having a plurality of pixel electrodes arranged at a main face of an insulating substrate, organic electroluminescent layers having a multi-layer structure respectively arranged above the plurality of pixel electrodes, a light transmitting opposed electrode arranged at an upper layer of the organic electroluminescent layer, and an insulating projection having a top surface and at least one sidewall extending at an angle with respect to the top surface arranged between respectives of the plurality of organic electroluminescent layers and including an organic electroluminescent display device element having a constitution of emitting light from a side of the opposed electrode; wherein an auxiliary electrode is extended on the opposed electrode along the insulating projection so as to cover at least a portion of the top surface of the insulating projection and to extend along and cover a portion of the at least one sidewall of the insulating projection at an angle corresponding to the extension angle of the at least one sidewall of the insulating projection and brought into contact with an upper portion of the opposed electrode; and wherein a width of the auxiliary electrode which extends along at least the portion of the top surface of the insulating projection from at least the covered portion of the at least one sidewall of the insulating projection is wider in at least one direction than a width of the top surface of the insulating projection in the at least one direction and is narrower than a greatest width of the entirety of the insulating projection in the at least one direction.
