Abstract

A display device with a touch detection function includes a display function layer, a plurality of touch detection electrodes arranged side by side to extend in a first direction, and a plurality of drive electrodes arranged side by side to extend in a second direction, electrostatic capacitance being formed at intersections of the touch detection electrodes and the drive electrodes. The plurality of drive electrodes extends to a first position or a second position outside of the first position, the first position being away from a center of an outermost touch detection electrode by a half length of an arrangement pitch of the touch detection electrodes, the outermost touch detection electrode being defined as outermost one of touch detection electrodes included in an effective display region of the display function layer, and an outer edge of the effective display region is located on or inside the first position.
