Abstract: 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.
