ABSTRACT:
A semiconductor device of the invention includes a data line, a power source line, a first scan line, a second scan line, a first transistor, a second transistor, a memory circuit, a third transistor, and a light-emitting element. A gate of the first transistor is connected to the data line, and a first terminal thereof is connected to the power source line; a gate of the second transistor is connected to the first scan line, and a first terminal thereof is connected to a second terminal of the first transistor; the memory circuit is connected to a second terminal of the second transistor and the second scan line; a first terminal of the third transistor is connected to the light-emitting element; and the memory circuit holds a first potential inputted from the power source line or a second potential inputted from the second scan line, and applies the potential to a gate of the third transistor to control emission
on-emission of the light-emitting element.
