Title: Display device

Abstract: To provide a highly reliable display device whose electrical element is applied with a low voltage. The display device is an active matrix FED display device whose pixel has an individual extraction gate electrode, an emitter array, a driving transistor which is connected to the emitter array in series, a potential control circuit which controls the potential of the extraction gate electrode, and a circuit which includes a switching element and a voltage holding element. By varying the potential of the extraction gate electrode in accordance with Vgs of the driving transistor, the active matrix driving method is performed by connecting a driving transistor to the emitter array in series and voltage which is applied to the driving transistor can be reduced.
