1. A proximity detection device comprising:
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 plurality of detection electrodes for proximity operation detection are arranged to form an operation surface at a position superposed on the display image surface, wherein each of the detection electrodes has a wavy-square pattern including:
a pair of wavy extending portions that extends in a first direction; anda pair of connector portions that extends in a second direction different from the first direction, wherein each of the detection electrodes has a wavy dummy pattern portion that is disposed inside the wavy-square pattern and that is surrounded by the pair of wavy extending portions and the pair of connector portions, wherein each of the wavy extending portions has first wavy slits of wavy lines having a constant waving pattern, and wherein the wavy dummy pattern portion is divided by second wavy slits of wavy lines having the constant waving pattern. |
