Abstract:
1. A semiconductor device comprising: a first transistor; a second transistor; a capacitor; a light-emitting element; 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 a 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 a source and a drain of the second transistor and the 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 each of the first transistor and the second transistor comprises an oxide semiconductor, and wherein an off-state current of the first transistor is 10
