Abstract: A difference between a length Ls of a slit and a length Ld of a dummy electrode is within ±15% of the length Ld. A difference between a length Le in the first direction of a portion between the slits adjacent to each other in the first direction in a detection electrode and the length Ld of the dummy electrode is within ±15% of the length Ld. A difference between a width Ws of the slit and a gap Dde between the dummy electrode and the detection electrode adjacent to each other in the second direction is within ±15% of the gap Dde. A difference between a width We in the second direction of a portion obtained by dividing the detection electrode by the slit and a width Wd of the dummy electrode is within ±15% of the width Wd.

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.

Abstract: A manufacturing method of a touch panel includes the steps of providing a substrate, forming a first conductive film on the substrate, forming a first mask on the first conductive film, etching the first conductive film to form electrode portions and lower intersect portions of the touch panel, forming an insulating film made of a negative resist on the first conductive film, and forming a contact hole above the electrode portion by removing the insulating film. The steps further include forming a second conductive film on the insulating film, forming a second mask on the second conductive film, etching the second conductive film to form an upper intersect portion connected between two adjacent electrode portions via the contact hole and intersecting with the lower intersect portion, and forming protective film on the second conductive film.
