LIGHT-EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light-emitting device in which variation in luminance among pixels caused by variation in threshold voltage of transistors can be suppressed.SOLUTION: 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 element maintaining a potential difference between one of a source and a drain of the transistor and the first gate; a second capacitor element 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 wiring; and a light-emitting element to which drain current of the transistor is supplied.
