Abstract: A light-transmitting substrate configuring an input device has a light-transmitting region where electrode parts and light-transmitting wiring parts are formed, and a light-non-transmitting region where light-non-transmitting wiring parts are formed. The light-transmitting region surrounded by an upper end side, both lateral sides, and a bonding boundary part (bend part) is bonded to a panel. The light-non-transmitting region of the substrate is bent inward of a housing from the bonding boundary part (bend part) as a start point, and is connected to a circuit board. The light-transmitting wiring parts are formed of a flexible light-transmitting conductive material layer, and hence the substrate can be bent in the light-transmitting region.

Abstract: First and second substrates are disposed to face each other and allowed to approach each other. A plurality of first electrodes are formed on the first substrate. A plurality of second electrodes are formed on the second substrate and face the respective first electrodes. A facing electrode pair is constituted by each of the first electrodes and a corresponding one of the second electrodes. A switching unit causes each of the first electrodes and each of the second electrodes to be connected to a driving unit or a detecting unit and switches between a first detection state in which a distance change between each of the first electrodes and a corresponding one of the second electrodes is detected and a second detection state in which the coordinates of a position that an operating body approaches or touches are determined in accordance with detection outputs from the facing electrode pairs.
