Abstract: An organic EL display device includes: a lower electrode; an upper electrode; a first organic layer which is disposed between the lower electrode and the upper electrode and is formed of a plurality of layers including a light emitting layer formed of an organic material that emits light; a metal wire that extends between the pixels within the display region; and a second organic layer which is formed of a plurality of layers the same as that of the first organic layer and which comes into contact with a part of the metal wire and does not come into contact with the first organic layer. The upper electrode comes into contact with the metal wire in the periphery of the second organic layer. Accordingly, it is possible to uniformize the potential of the upper electrode without reducing the light emission area.
