Claim:
1. A display apparatus with a touch detection function comprising: a substrate; a display area that includes a plurality of pixels arranged in a plane parallel to a principal surface of the substrate; a touch detection electrode that includes a plurality of small electrode portions arranged in a plane parallel to the principal surface of the substrate, the small electrode portions each including a plurality of conductive thin wires; a plurality of wiring portions that electrically couple the small electrode portions to a terminal portion formed outside the display area; a dummy electrode portion extending in a first direction and being disposed between the small electrode portions that are adjacent in a second direction intersecting the first direction, the dummy electrode portion including a plurality of dummy electrodes comprising thin wire fragments disposed separately from each other; and a plurality of drive electrodes that form capacitance between the drive electrodes and the touch detection electrode: a drive signal driver that supplies a drive signal to a first group of electrodes that are a part of the small electrode portions in a display period in which an image is displayed in the display area and a touch detection unit that detects contact or proximity of an object on the basis of a signal appearing on a second group of electrodes that are a different part of the small electrode portions via mutual capacitance between the first group of electrodes and the second group of electrodes, in the display period, wherein each of the plurality of conductive thin wires includes a first thin wire segment and a second thin wire segment that are coupled in the first direction, each of the wiring portions includes the first thin wire segment and the second thin wire segment of one of the plurality of conductive thin wires that are coupled in the first direction, each first thin wire segment makes a first angle with respect to the first direction, and each second thin wire segment makes a second angle with respect to the first direction.
