INPUT DEVICE, DISPLAY DEVICE WITH INPUT FUNCTION, AND ELECTRONIC APPARATUS
An input device includes: a resistive film type input unit; and a non-contact type input unit that overlaps at least a portion of the resistive film type input unit. The resistive film type input unit includes: first and second substrates each having a first surface and a second surface; a first electrode that is formed on the first surface of the first substrate; and a second electrode that is formed on the first surface of the second substrate. The second substrate is provided on an input operation side of the first substrate, and the first electrode of the first substrate faces the second electrode of the second substrate. The resistive film type input unit is in a standby state that does not perform input detection until an input to the non-contact type input unit is detected. When the input to the non-contact type input unit is detected, the resistive film type input unit is turned on to perform input detection.
