Abstract
A proximity detection device includes a display unit which has a display image surface in which a plurality of pixel electrodes are arranged in a matrix shape and a proximity operation detecting unit in which a transparent electrode for proximity operation detection is arranged to form an operation surface at a position superposed on the display image surface and a conductive film pattern forming the transparent electrode has a pitch of a linear pattern which is equal to or smaller than an arrangement pitch in one direction of the pixel electrodes.
