Abstract: According to an aspect, a display device with a touch detection function includes: a substrate; a touch detection electrode of a translucent conductor; a dummy electrode of the translucent conductor provided in a region where the touch detection electrode is not provided; and a drive electrode having capacitance with respect to the touch detection electrode. The dummy electrode comprises: a first direction slit dividing the dummy electrode so that pieces of the dummy electrode are adjacent to each other in a second direction; and a plurality of second direction slits each dividing the dummy so that the pieces of the dummy electrode are adjacent to each other in the first direction. The second direction slits include a first linear slit having a first angle and a second linear slit having a second angle different from the first angle.
