DISPLAY DEVICE

To provide a display device capable of stably forming various types of ID patterns even when it has a configuration for reducing reflection from a surface of wiring so as to be used outdoors.SOLUTION: A display device comprises: laminated wiring configured of a conductive film and an antireflection film successively disposed on a ground layer; a wiring terminal part disposed on an end part of the laminated wiring; and an insulation film covering the laminated wiring and the wiring terminal part, therein the insulation film side becomes a display face side. The wiring terminal part is configured of the conductive film, and a first opening which penetrates the insulation film, and reaches the conductive film is provided on the wiring terminal part, and an outer edge part of the first opening includes a laminated structure of the conductive film and the insulation film and at least one of a mark and an identification symbol to be used in a manufacturing process in at least a part thereof, and at least one of the mark and the identification symbol is configured of the conductive film, and covered with the insulation film.SELECTED DRAWING: Figure 25 【課題】屋外で使用するために配線表面からの反射を低減する構成を有していても、各種のＩＤパターンを安定して形成できる表示装置を提供する。【解決手段】下地層上に順に配設された導電膜と、反射防止膜とで構成される積層配線と、積層配線の端部に設けられた配線端子部と、積層配線および配線端子部を覆う絶縁膜と、を備え、絶縁膜側が表示面側となる表示装置であって、配線端子部は、導電膜で構成され、配線端子部において、絶縁膜を貫通して導電膜に達する第１の開口部が設けられ、第１の開口部の外縁部は、少なくとも一部において、導電膜および絶縁膜の積層構造と、製造工程で使用されるマークおよび識別記号の少なくとも一方と、を有し、マークおよび識別記号の少なくとも一方は、導電膜で構成され、絶縁膜で覆われる。【選択図】図２５
