Abstract: A sensor-equipped display device is provided and includes a display panel and a detection electrode. The panel includes a display area in which unit pixels are arranged in a matrix, each of unit pixels including subpixels. The electrode includes conductive line fragments arranged on a detection surface, and is configured to detect a contact of an object to the surface. The detection electrode has an electrode pattern formed of the line fragments on a grid defined by first and second lines. Extending directions of the first and second lines are tilted based on a first and second unit length of the unit pixel in the first and second direction.

Abstract: Detection electrode wirings formed by an ITO film have a high resistance and the detection capability thereof is degraded with the increase of the size and/or resolution. A manufacturing method of a display device includes: (a) arranging liquid crystal between an array substrate and a counter substrate; (b) forming a metal layer and a low-reflection layer on the counter substrate after the step (a); (c) applying an overcoat film onto the metal layer and the low-reflection layer; and (d) curing the overcoat film to form a protection layer. The step (d) cures the overcoat film with light and heat.

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.
