Claim Text:
1. An organic EL display device comprising: a display region including a plurality of pixels respectively having a light-emitting device which is stacked respectively in order of an organic layer including a first electrode and a light-emitting layer, and a second electrode from a substrate side; a peripheral region that is arranged on an outer edge side of the display region, and has a peripheral circuit; a first insulating layer of a lower layer side and a second insulating layer of an upper layer side that are arranged so as to be extended to the peripheral region from the display region; a first separation groove that is arranged in the first insulating layer between the display region and the peripheral region; a first conductive layer that is arranged on the first insulating layer of the peripheral region, through a bottom portion from a side face of the first separation groove; a first covering portion where at least an end face of the second insulating layer is covered by the organic layer or the second electrode; a sealing portion that is arranged on an outer edge side of the first covering portion, and is configured by stacking the first conductive layer and the second electrode; a second covering portion where an end face of an outer edge side of the first insulating layer which is separated from the peripheral region side by the first separation groove, is covered by the first conductive layer; a second conductive layer that is arranged between the substrate and the first insulating layer; a third insulating layer that is arranged between the second conductive layer and the first insulating layer, the third insulating layer being separated by the first separation groove with the first insulating layer; and a connection portion that is arranged in the bottom portion of the first separation groove, the connection portion includes a stack having the first conductive layer and the second conductive layer.
