    Abstract: A display device includes a first substrate, a second substrate, a display functional layer, first electrodes, pixel electrodes, second electrodes, a drive circuit, and a conductive body. The second substrate faces the first substrate. The display functional layer is provided between the first substrate and the second substrate. The first electrodes are provided between the first substrate and the second substrate. The pixel electrodes face the first electrodes between the first substrate and the second substrate. The second electrodes overlap the first electrodes through the display functional layer. The drive circuit supplies drive signals to a pair of the first electrode, wherein the drive circuit supplies a first electric potential to one of the pair of first electrodes and supplies a drive signal having a second electric potential different from the first electric potential to the other of the pair of first electrodes simultaneously.

    Abstract: According to an aspect, a display device includes: a plurality of pixels aligned in row and column directions, each of the pixels including a drive element; a plurality of scan lines each coupled with the drive elements included in the pixels aligned in the row direction to transmit thereto a scan signal for selecting the pixels row by row; a plurality of signal lines each coupled with the drive elements included in the pixels aligned in the column direction to write display data; and a display control unit. The display control unit alternately repeats a display period and a stop period. In a latter term of the stop period, display control unit provides the display data written in the respective pixels in a row that has been selected during the display period immediately before the stop period, to the signal lines corresponding to the respective pixels.
