    Abstract: A display apparatus includes a first substrate, a second substrate, a display functional layer, first electrodes, second electrodes, third electrodes, and a drive circuit. The second substrate faces the first substrate. The display functional layer is provided between the first substrate and the second substrate and used to display an image in a display area. The first electrodes are provided in the display area between the first substrate and the second substrate. The second electrodes are provided, facing the first electrodes, in the display area on the surface of the second substrate. The third electrodes are provided in a frame area on the outer side of the display area. The drive circuit supplies a first drive signal to at least one of the first electrodes and the second electrodes.
