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 is 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.

Abstract: A terminal structure that keeps the resistance of its connecting portion small and secures mechanical reliability is to be achieved. A display device includes a display region and a terminal region. A terminal formed in the terminal region is formed with a terminal metal, a first oxide conductive film covering the end portion of the terminal metal, and a second oxide conductive film covering the first oxide conductive film and the terminal metal. The first oxide conductive film has an opening in the center part of the terminal.
