摘要： The present invention disposes a switch transistor between a driving transistor and a light emitting element, and sets the switch transistor in an off state during a non-emission period. Thereby, a variation in threshold voltage of the driving transistor is corrected while destruction of the light emitting element due to a reverse bias is avoided.
