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: A display device includes: a display panel including panel terminals; and a wiring substrate including first substrate terminals coupled to the panel terminals. The panel terminals include panel terminals arranged in a first region and panel terminals arranged in second regions sandwiching the first region. The first substrate terminals include first substrate terminals arranged in a third region and first substrate terminals arranged in fourth regions sandwiching the third region. A gap between panel terminals is substantially constant in the first and second regions. A first width of the panel terminals in the first region is different from a second width of the panel terminals in the second regions. A width of the first substrate terminals is substantially constant in the third and fourth regions. A first gap between first substrate terminals in the third region is different from a second gap between first substrate terminals in the fourth regions.
