Abstract: According to one embodiment, a detection device includes a substrate, detection electrode, terminal formed of a metal material, lead, coating layer, conductive adhesion layer, and circuit board. The lead connects the electrode and the terminal. The coating layer covers the electrode and the lead, and partly covers the terminal. The adhesion layer covers a part of the terminal exposed from the coating layer and covers a part of the coating layer. The circuit board is connected to the terminal with the adhesion layer interposed therebetween. At least in an overlapping area where the adhesion layer covers the coating layer, an area of the metal material per unit area is smaller than that of the other area of the terminal.

Abstract: To reduce disturbances in display of images due to static electricity without deteriorating optical properties in a display. The display includes a conductive pattern provided on the upper surface of the substrate, a protection layer provided on the upper surface of the substrate to cover the conductive pattern, and a conductive layer provided on the protection layer. The sheet resistance of the conductive pattern is not more than 8 Ω/square. A ratio of the total sum of areas of portions of the plurality of sub-pixels that overlap the conductive pattern in a plan view to the total sum of the areas of the plurality of sub-pixels is 1 to 22%. A sheet resistance of the conductive layer is higher than the sheet resistance of the conductive pattern.

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.
