Abstract
According to an aspect, a display device with a touch detection function includes: a substrate; a drive electrode that extends in a first direction; and a plurality of touch detection electrodes that are metal wirings extending in a second direction different from the first direction. The metal wirings are arranged with a predetermined pitch so as to make capacitive coupling with the drive electrode.
