Abstract
An electrostatic capacitance input device having a plurality of first electrodes extending in a first direction and a plurality of second electrodes extending in a second direction intersecting the first direction in an input area, including a plurality of first lines extending in parallel to each other from the plurality of first electrodes to a plurality of first terminals, and a plurality of second lines extending in parallel to each other from the plurality of second electrode to a plurality of second terminals, the first lines and the second lines being formed outside the input area, and an auxiliary line extending outside at least one of the lines at both ends in terms of the direction of arrangement of one or both of the plurality of first lines and the plurality of second lines, the auxiliary line generating a parasitic capacitance with respect to the at least one of the lines.
