摘要: A semiconductor device with less power consumption and an electronic appliance using the same. The semiconductor device of the invention is supplied with a first potential from a high potential power source and a second potential from a low potential power source. Upon input of a first signal to an input node, an output node outputs a second signal. With the semiconductor device of the invention, a potential difference of the second signal can be controlled to be smaller than a potential difference between the first potential and the second potential, thereby power consumption required for charging/discharging wires can be reduced.

摘要: 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.

摘要: A problem in that a light emitting element slightly emits light is solved by an off current of a thin film transistor connected in series to the light emitting element, thereby a display device which can perform a clear display by increasing contrast, and a driving method thereof are provided. When the thin film transistor connected in series to the light emitting element is turned off, a charge held in the capacitance of the light emitting element itself is discharged. Even when an off current is generated at the thin film transistor connected in series to the light emitting element, this off current charges this capacitance until the capacitance of the light emitting element itself holds a predetermined voltage again. Accordingly, the off current of the thin film transistor does not contribute to light emission. In this manner, a slight light emission of the light emitting element can be reduced.
