Abstract:
1. A light-emitting device comprising: a light-emitting element; a first transistor whose first terminal is electrically connected to a first terminal of the light-emitting element and whose second terminal is electrically connected to a first line; a second transistor whose first terminal is electrically connected to a gate of the first transistor and whose second terminal is electrically connected to a second line; a third transistor whose first terminal is electrically connected to the second terminal of the first transistor and whose second terminal is electrically connected to the gate of the first transistor; a fourth transistor whose first terminal is electrically connected to the first terminal of the light-emitting element and whose second terminal is electrically connected to a third line; a first capacitor whose first terminal is electrically connected to the gate of the first transistor and whose second terminal is electrically connected to the first terminal of the light-emitting element; and a second capacitor whose first terminal is electrically connected to the first terminal of the light-emitting element, wherein a second terminal of the second capacitor is electrically connected to the third line, and wherein the first to third transistors are n-channel transistors.
