Abstract: A display device includes a display panel having a display area where subpixels for emitting light in different colors are arranged in a matrix shape, the display panel having a peripheral area where terminals and a drive circuit are formed; and metal lines for touch sensing on the display panel. The display panel has a non-rectangular shape with a curve part of a contour in a plan view. The metal lines extend in at least two directions and cross at portions to form a mesh shape. The subpixels include some subpixels arranged stepwise in an outline area of the display area next to the curve part of the contour. None of the metal lines is formed on the subpixels arranged stepwise.

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.

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: In a capacitive touch panel, edge regions of the panel display generally have poor accuracy of coordinate detection of a touch point as compared to the intermediate region of the panel display. A display device includes a plurality of first electrodes arranged at predetermined pitches and extending in a X-direction; and a plurality of second electrodes arranged at predetermined pitches and extending in a Y-direction, wherein both endmost first electrodes of the plurality of first electrodes have a smaller pitch than the other first electrodes, both endmost second electrodes of the plurality of second electrodes have a smaller pitch than the other second electrodes, and the display device is configured to detect a touch based on a capacitance variation at one or more of intersections of the plurality of first electrodes with the plurality of second electrodes.

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.
