Organic electroluminescence display device
View Patent ↗An insulating layer is disposed in areas between pixel electrodes adjacent to each other so as to rest on peripheries of the pixel electrodes. An organic layer is disposed to include a common layer that continuously covers the pixel electrodes and the insulating layer. A common electrode is disposed on the organic layer. A sealing layer conducts sealing to cover the organic layer and the common electrode. The pixel electrodes have depressed portions whose upper surfaces are recessed on ends including the peripheries of the pixel electrodes. The common layer has depressed portions whose upper surfaces are recessed in correspondence with the depressed portions of the pixel electrodes. The common electrode has depressed portions whose upper surfaces are recessed in correspondence with the depressed portions of the common layer. The sealing layer is curved in correspondence with the depressed portions of the common electrode.
