摘要： A display device which can compensate for variations of the threshold voltage of transistors and suppress variations in luminance, and a driving method thereof are provided. Current is supplied to a light emitting element and light is emitted from the light emitting element by following steps: in the first period initial voltage is stored in a storage capacitor; in the second period, voltage based on video signal voltage and the threshold voltage of the transistor is stored in the storage capacitor; and in the third period, the voltage stored in the storage capacitor in the second period is applied to a gate electrode of the transistor. By these operation processes, the current which compensates the effect of the variations of the threshold voltage of the transistor can be supplied to the light emitting element. Therefore, variations in luminance are suppressed.

摘要： An object is to provide a driving method of a liquid crystal display device with a low power consumption and a high image quality. A pixel includes a liquid crystal element and a transistor which controls supply of an image signal to the liquid crystal element. The transistor includes, in a channel formation region, a semiconductor which has a wider band gap than a silicon semiconductor and has a lower intrinsic carrier density than silicon, and has an extremely low off-state current. In inversion driving of pixels, image signals having opposite polarities are input to a pair of signal lines between which a pixel electrode is disposed. By employing such a structure, the quality of the displayed image can be increased even in the absence of a capacitor in the pixel.
