Abstract: According to an aspect, a display device with a touch detecting function includes: a display area in which pixels each composed of a plurality of color areas are arranged in a matrix; a touch detection electrode including a first conductive thin wire extending in a first direction; and a dummy electrode including a plurality of second conductive thin wires; a drive electrode having capacitance for the touch detection electrode. Each of the second conductive thin wires includes a plurality of thin wire pieces extending in a direction different from the first direction and is divided by a slit between the thin wire pieces. A color area in the display area with which the slit overlaps has a different color from a color area in the display area with which a slit closest to the slit in a second direction orthogonal to the first direction overlaps.
