Abstract: In a seal part where a translucent opposite substrate and an element substrate are bonded together, a peripheral member is provided in such a manner as to be buried in a sealing member. This prevents the sealing member from breaking, thus making it possible to make the seal part durable to improve the strength of the panel. Further, an output wiring connected to an electrode pattern of a sensing unit can be protected by being covered with a protective insulating layer. The peripheral member and the protective insulating layer can be formed by the same insulating material. This makes it possible to simplify the process to reduce production costs.

Abstract: An organic electroluminescent display device includes a first substrate having a pixel area including a plurality of pixels each including a plurality of sub pixels, a light emitting devices are provided in correspondence with the sub pixels, and a partition layer covering a peripheral portion of each of the sub pixels; and a second substrate having a sensing unit including a first electrode pattern extending in one direction and a second electrode pattern extending in a direction intersecting the one direction, and the first electrode pattern and the second electrode pattern is provided out of contact from each other. The first electrode pattern is located to overlap the partition layer so as to enclose the sub pixels. The first electrode pattern included in the sensing unit encloses the sub pixels, and thus light is prevented from leaking to adjacent sub pixels.

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.
