Abstract
Degradations in light emitting elements occur with the passage of time. A method of driving a light-emitting device is characterized by including the steps of: supplying a light-emitting element with the current in response to an analog video signal during a sustaining period; and turning switch off thereby to make the light-emitting element nonluminous or making first and the second electrodes identical in potential thereby to make the light-emitting element nonluminous during an off time period.
