Patent ID: 8872868

Claim:
A driving method of a light emitting device comprising a first transistor, a second transistor, a wiring, and a light emitting element, wherein each of n subframe periods (n is a natural number equal to or more than two) comprises a writing operation period and a light emitting period following the writing operation period, wherein one of source and drain of the first transistor is electrically connected to the wiring and the other of source and drain of the first transistor is electrically connected to a gate of the second transistor, and wherein one of source and drain of the second transistor is electrically connected to the light emitting element, the driving method comprising the steps of: inputting a first erasing signal to the gate of the second transistor in at least one of the n subframe periods; and inputting a second erasing signal to the gate of the second transistor in the at least one of the n subframe periods.
