Display device and electronic device

A display device comprising:

• a first circuit comprising a first transistor, a second transistor, a third transistor, and a first capacitor;
• and
• a pixel comprising a fourth transistor,
• wherein the first transistor, the second transistor, and the third transistor are positioned outside a display region,
• wherein the first capacitor and the pixel are positioned in the display region,
• wherein the first circuit is configured to generate third data by adding first data and second data,
• wherein the pixel is configured to perform display in accordance with the third data,
• wherein one of a source and a drain of the first transistor is electrically connected to one of a source and a drain of the fourth transistor and one electrode of the first capacitor,
• wherein the other electrode of the first capacitor is electrically connected to one of a source and a drain of the second transistor and one of a source and a drain of the third transistor,
• wherein the other of the source and the drain of the first transistor is electrically connected to the other of the source and the drain of the second transistor, and
• wherein the first capacitor comprises a plurality of second capacitors which are electrically connected in parallel.
