Display device with touch detection function
According to an aspect, a display device with a touch detection function includes: a plurality of pixel electrodes arranged in a matrix; a plurality of scanning signal lines; a drive electrode that faces the pixel electrodes; and a plurality of touch detection electrodes including a detection electrode pattern of a transparent conductive body that faces the drive electrode. The detection electrode pattern includes one or more slits each of which is a region where the transparent conductive body is not present. The slits of the detection electrode pattern of the touch detection electrodes extend in a direction different from an extending direction of the scanning signal lines with a slit pitch having a predetermined interval therebetween in the extending direction of the scanning signal lines. The slit pitch is multiples of a natural number of a predetermined pixel pitch in which the pixel electrodes are arranged.

a plurality of scanning signal lines extending in the first direction to supply a scanning signal for driving the pixels;
a plurality of pixel signal lines that extend on a plane parallel to a surface of the substrate to supply a pixel signal for displaying an image to the pixels; and
a plurality of touch detection electrodes each including a transparent conductive body that faces the substrate in the vertical direction,
wherein
a slit is disposed between two of the touch detection electrodes,
