Patent ID: 8237357

Claim:
An organic electroluminescent device comprising: partition walls dividing a region into a first region, a second region, and a third region; a first organic layer disposed in the first region; a second organic layer disposed in the second region; and a third organic layer disposed in the third region, the first region including: a plurality of effective pixels involved in light emission, continuously disposed along a first aligning axis and not separated by partition walls, each effective pixel including an effective pixel electrode, a common electrode, and the first organic layer between the effective pixel electrode and the common electrode; a first dummy pixel including a fourth organic layer and a second dummy pixel including a fifth organic layer that are not involved in light emission and are disposed along the first aligning axis such that the effective pixels lie between the first dummy pixel and the second dummy pixel; and an inorganic bank layer having openings corresponding to shapes of the plurality of effective pixels and the first and second dummy pixels, the inorganic bank layer separating the plurality of effective pixels and the first and second dummy pixels, where the second region and the third region oppose each other with the first region therebetween, and the first region, the second region and the third region are aligned along the first aligning axis.
