ABSTRACT:
The amplitude of a potential of a signal line is decreased and a scan line driver circuit is prevented from being excessively loaded. A light-emitting device includes a light-emitting element; a first power supply line having a first potential; a second power supply line having a second potential; a first transistor for controlling a connection between the first power supply line and the light-emitting element; a second transistor, which is controlled in accordance with a video signal, whether outputting the second potential applied from the second power supply line or not; a switching element for selecting either the first potential applied from the first power supply line or the output of the second transistor; and a third transistor for selecting whether the first potential or the output of the second transistor which is selected by the switch is applied to a gate of the first transistor.
