Display device and electronic device

A display device comprising a pixel, the pixel comprising:

• a first transistor, a second transistor, a third transistor, a fourth transistor, a first capacitor, and a display element,
• wherein each of the first transistor, the second transistor, and the third transistor comprises a gate and a back gate,
• wherein the fourth transistor comprises a gate and does not comprise a back gate,
• wherein the gate and the back gate of the first transistor are electrically connected to a first gate line,
• wherein the gate and the back gate of the second transistor are electrically connected to a second gate line,
• wherein one of a source and a drain of the first transistor is electrically connected to a first wiring,
• wherein one of a source and a drain of the second transistor is electrically connected to a second wiring,
• 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,
• wherein the other of the source and the drain of the first transistor is electrically connected to one electrode of the first capacitor,
• wherein the other of the source and the drain of the second transistor is electrically connected to the one electrode of the first capacitor,
• wherein one of a source and a drain of the third transistor is electrically connected to one of a source and a drain of the fourth transistor, and
• wherein the other of the source and the drain of the fourth transistor is electrically connected to the display element.
