Abstract
An organic electroluminescent display device includes a first insulating layer that buries a peripheral portion of a first electrode and has an opening exposing an area of the first electrode inner to the peripheral portion thereof; a second electrode that is in contact with the first electrode in the opening and is provided continuously on a top surface of the first electrode and onto a top surface of the first insulating layer; a second insulating layer covering a peripheral portion of the second electrode; an organic EL layer; and a third electrode. The second electrode includes a stepped portion. An area where the stepped portion is included and the second electrode, the organic electroluminescence layer and the third electrode overlap each other is a light emitting area. Light emitted by the organic EL layer is reflected by the stepped portion.
