Display apparatus that includes electrodes in a frame area

A display apparatus comprising:

• a first substrate;
• a second substrate facing the first substrate;
• a display functional layer provided between the first substrate and the second substrate and configured to display an image in a display area;
• first electrodes provided in the display area between the first substrate and the second substrate;
• second electrodes provided in the display area on a surface of the second substrate, the second electrodes facing the first electrodes, wherein the second electrodes are divided into a first group of second electrodes that includes at least one of the second electrodes and a second group of second electrodes that includes the remaining second electrodes;
• third electrodes provided in a frame area on an outer side of the display area;
• and
• a drive circuit configured to supply a first drive signal to the first electrodes and the second group of second electrodes in a first detection period,
• wherein, in the first detection period, the third electrodes output a first detection signal based on a change in capacitance between the third electrodes and at least one of:
• the first electrodes that overlap the second electrodes;
• or
• the second group of second electrodes;
• and
• wherein, in the first detection period, the first group of second electrodes outputs a second detection signal based on a change in capacitance between the first electrodes and the first group of second electrodes.
