  • Patent number: 9666829
    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.

  • Patent number: 9665194
    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.
