ABSTRACT:
According to a driving method of applying a reverse bias voltage, capacitance occurs due to a stacked structure of a conductor, an insulator and a conductor, or due to a structure of a TFT. This capacitance prevents normal operation. The invention provides a pixel configuration including at least a driving transistor for driving a light emitting element and a switching transistor for controlling the driving transistor, wherein the switching transistor is turned on in the case of applying a forward bias voltage after applying a reverse bias voltage. As a result, it is prevented that the potential changes due to unwanted capacitive coupling.
