Abstract: According to an aspect, a detection device includes: a substrate; a detection electrode disposed on a plane parallel to a surface of the substrate and including conductive thin wires and electrical coupling portions disposed where the conductive thin wires intersect with each other or are bent, and are coupled with each other, the conductive thin wires being arranged in a mesh-like form; a coupling wire that couples the conductive thin wires with a detecting unit at an end portion of the detection electrode; and a protective layer that is made of an insulation material and that covers the detection electrode and the coupling wire. An area density of the conductive thin wires per unit area is smaller in an end region ranging from an electrical coupling portion closest to the coupling wire to the coupling wire than in a region of the entire detection electrode.

Abstract: A touch panel includes a plurality of first electrodes, a plurality of second electrodes, and a plurality of wirings. Each of the plurality of first electrodes has a first portion formed on a layer different from that on which the second electrodes are formed and intersecting the second electrodes, and a second portion formed on the same layer as that on which the second electrodes are formed, but separated from the second electrode. The second electrode and the second portion of the first electrode are formed on a layer different than the layer where the wiring is formed. The first portion of the first electrode is connected to the second portion through a contact portion formed in an insulating film made of a negative resist between the first portion and the second electrode.
