Patent ID: 8803768

Claim:
A semiconductor device comprising: a first transistor; a storage capacitor; a first switch; a second switch; a third switch; a fourth switch; and a fifth switch, wherein one of a source and a drain of the first transistor is directly connected to a first electrode of a light-emitting element, wherein the other of the source and the drain of the first transistor is electrically connected to a first wiring through the second switch, wherein the other of the source and the drain of the first transistor is electrically connected to a gate of the first transistor through the third switch, wherein the other of the source and the drain of the first transistor is directly connected to the second switch and the third switch, wherein the gate of the first transistor is electrically connected to a second wiring through the storage capacitor and the fourth switch, wherein the gate of the first transistor is electrically connected to a third wiring through the storage capacitor and the first switch, wherein the one of the source and the drain of the first transistor is electrically connected to a fourth wiring through the fifth switch, and wherein a potential of the fourth wiring is lower than a potential of a second electrode of the light-emitting element.
