1. A display device with a touch detection function comprising:

  • a substrate;

    a plurality of pixels that are arranged in a matrix of a first direction and a second direction on a plane parallel to a surface of the substrate, the pixels each having a plurality of sub-pixels including a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel arranged in the second direction;

    a plurality of pixel electrodes each corresponding to a sub-pixel of the plurality of sub-pixels;

    a plurality of signal lines that extend in a first direction on a plane parallel to the surface of the substrate and supply pixel signals used for displaying an image to the pixel electrodes;

    a display functional layer that performs an image displaying function based on the pixel signals;

    a drive electrode that faces the plurality of the pixel electrodes in a vertical direction with respect to the surface of the substrate and extends in the first direction;

    a plurality of touch detection electrodes each being a metal wire and each extending in the second direction, wherein the touch detection electrodes are arranged in the first direction and face the drive electrode in the vertical direction; and

    a plurality of dummy electrodes each being a metal wire of a same material with the touch detection electrodes and each extending in the second direction, wherein the dummy electrodes are arranged in the first direction and are not connected to a touch detection unit which detects a touch based on a detection signal from the touch detection electrodes,whereineach of the touch detection electrodes and the dummy electrodes extends in the second direction in which the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel are arranged, and does not extends in the first direction in which each of the signal lines extends such that the touch detection electrodes do not cross each other and that the dummy electrodes do not cross each other, andthe metal wires including the dummy electrodes and the touch detection electrodes are arranged at intervals of a natural number multiple of a first pixel pitch of the pixel electrodes in the first direction.
