Patent abstract
To provide a light-emitting device in which variation in luminance among pixels caused by variation in threshold voltage of transistors can be suppressed. The light-emitting device includes a transistor including a first gate and a second gate overlapping with each other with a semiconductor film therebetween, a first capacitor maintaining a potential difference between one of a source and a drain of the transistor and the first gate, a second capacitor maintaining a potential difference between one of the source and the drain of the transistor and the second gate, a switch controlling conduction between the second gate of the transistor and a wiring, and a light-emitting element to which drain current of the transistor is supplied.
