Display device with touch detection function and electronic unit
First Claim
1. A display device with a touch detection function comprising:
- 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 intersecting with the first direction, electrostatic capacitance being formed at intersections of the touch detection electrodes and the drive electrodes, whereinthe 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, andan outer edge of the effective display region is located on or inside the first position.
