Abstract: A position input device includes electrodes formed of metal with a belt-like shape, extended along a first direction, and arranged with a space therebetween along a second direction that is orthogonal to the first direction, lines each electrically connected to one end of each of the electrodes in the first direction to receive a signal, dummy electrodes formed of metal with a belt-like shape and each disposed in a space between the electrodes that are adjacent, and dummy lines each coupled to an end of each of the dummy electrodes in the first direction in an electrically disconnected state. The electrodes, the lines, the dummy electrodes, and the dummy lines each include a front side surface and a back side surface in a plane along the first direction and the second direction, and at least one of the front side surface and the back side surface is blackened.

Abstract: A touch panel display device includes a display panel and a touch panel. The touch panel includes a plurality of first electrodes, at least one set of auxiliary electrodes, and a plurality of second electrodes. The touch panel further includes a plurality of first wires connected to ends of the plurality of first electrodes and the at least one set of auxiliary electrodes, and a plurality of second wires connected to ends of the plurality of second electrodes. Some of the plurality of first electrodes and the remaining electrodes have ends opposite to each other in an extending direction of the first electrodes and respectively connected to the first wires. The one set of auxiliary electrodes are provided between the first electrodes adjacent to each other and having opposite ends connected to the first wires, and have opposite ends connected to corresponding ones of the first wires.
