Abstract

According to one embodiment, an organic EL device includes an insulating substrate, first and second interlayer insulators, pixel electrodes, an organic layer, and a counter electrode. The first interlayer insulator is positioned above the insulating substrate. The second interlayer insulator is positioned on the first interlayer insulator and provided with slits. The pixel electrodes are arranged on the second interlayer insulator. Two or more of the pixels are adjacent to each other with one of regions corresponding to the slits interposed therebetween. The organic layer is positioned on the pixel electrodes and includes an emitting layer. The counter electrode is positioned above the organic layer.
