1. A semiconductor device comprising:
first and second transistors, first to fifth switches, first to third capacitors, and a display element,
wherein the first transistor comprises a back gate,
wherein a gate of the first transistor is electrically connected to the first switch,
wherein the second switch and the first capacitor are positioned between the gate of the first transistor and a source of the first transistor,
wherein the back gate of the first transistor is electrically connected to the third switch,
wherein the second capacitor is positioned between the back gate of the first transistor and the source of the first transistor,
wherein the source of the first transistor is electrically connected to the fourth switch and a drain of the second transistor,
wherein a gate of the second transistor is electrically connected to the fifth switch,
wherein the third capacitor is positioned between the gate of the second transistor and a source of the second transistor, and
wherein the source of the second transistor is electrically connected to the display element.
