Abstract
An electrostatic capacitance-type input device in which input position detecting electrodes are disposed in an input area of a substrate, includes a lower layer-side conductive film, an interlayer insulating film, and an upper layer-side conductive film, which are stacked on the substrate in order from the substrate side. A first input position detecting electrode and a second input position detecting electrode are formed as the input position detecting electrodes by a first conductive film out of the lower and upper layer-side conductive films. A relay electrode overlaps with the first input position detecting electrode in the intersection portion to be electrically connected to the discontinued portion of the second input position detecting electrode. An input area shield electrode that overlaps with the first and second input position detecting electrodes are formed by a second conductive film out of the lower and upper layer-side conductive films.
