PROBLEM TO BE SOLVED: To provide a light-emitting device in which variation in luminance of pixels caused by variation in threshold voltage of transistors is suppressed.SOLUTION: A light-emitting device includes at least transistors 11-15, first wiring, second wiring, a first switch, a second switch, a third switch, a fourth switch, a capacitor 16, and a light-emitting element 17. The first switch has a function of selecting whether electrical continuity is established or not between the first wiring and one electrode of the capacitor. The other electrode of the capacitor is connected to one of a source and a drain of the transistor. The second switch has a function of selecting whether electrical continuity is established or not between the second wiring and a gate of the transistor. The third switch has a function of selecting whether electrical continuity is established or not between one electrode of the capacitor and the gate of the transistor. The fourth switch has a function of selecting whether electrical continuity is established or not between one of the source and the drain of the transistor and an anode of the light-emitting element. |
