Abstract:
1. An input device comprising: a plurality of input-position detecting electrodes arranged at a first interval along a first direction of a display plane; at least one driving electrode which is arranged so as to be opposed to the plurality of input-position detecting electrodes and forms an electrostatic capacitance with the plurality of input-position detecting electrodes; and an intermediate member disposed between the plurality of input-position detecting electrodes and the at least one driving electrode, wherein when an ideal value of a width of each of the plurality of input-position detecting electrodes in the first direction is defined as Wsmax [μm], the first interval which is a center-to-center distance of adjacent input-position detecting electrodes among the plurality of input-position detecting electrodes is defined as P [μm], and an effective inter-electrode distance represented by an inverse number of a value obtained by dividing a relative permittivity of the intermediate member by a thickness of the intermediate member is defined as D [μm], Wsmax is represented by a following formula: the width of each of the plurality of input-position detecting electrodes in the first direction falls within a range of not more than ±150 μm of a value of the Wsmax.
