Claim:
1. A semiconductor device comprising: a green light-emitting element; a red light-emitting element; a blue light-emitting element; a white light-emitting element; a first transistor, the first transistor comprising an oxide semiconductor in a channel region; a second transistor, the second transistor comprising: a third transistor; a capacitor; a first line; and a second line, wherein one of a source and a drain of the first transistor is electrically connected to the first line, wherein the other one of the source and the drain of the first transistor is electrically connected to the gate of the second transistor and one terminal of the capacitor, wherein the other one terminal of the capacitor is electrically connected to one of the source and the drain of the second transistor, one of a source and a drain of the third transistor, and the green light-emitting element, wherein the other one of the source and the drain of the second transistor is electrically connected to the second line, wherein the oxide semiconductor layer comprises In, Ga, and Zn, and wherein a gate of the first transistor is not directly connected to a gate of the third transistor.
