    Abstract: A semiconductor device including a capacitor whose charge capacity is increased while improving the aperture ratio is provided. Further, a semiconductor device which consumes less power is provided. A transistor which includes a light-transmitting semiconductor film, a capacitor in which a dielectric film is provided between a pair of electrodes, an insulating film which is provided over the light-transmitting semiconductor film, and a first light-transmitting conductive film which is provided over the insulating film are included. The capacitor includes the first light-transmitting conductive film which serves as one electrode, the insulating film which functions as a dielectric, and a second light-transmitting conductive film which faces the first light-transmitting conductive film with the insulating film positioned therebetween and functions as the other electrode. The second light-transmitting conductive film is formed over the same surface as the light-transmitting semiconductor film of the transistor and is a metal oxide film containing a dopant.

    Abstract: To provide a display device and a driving method thereof, where variations in the threshold voltage of transistors can be compensated and thus variations in luminance of light-emitting elements can be suppressed. In a first period, initialization is performed; in a second period, a voltage based on the threshold voltage of a first transistor is held in first and second storage capacitors; in a third period, a voltage based on a video signal voltage and the threshold voltage of the first transistor is held in the first and second storage capacitors; and in a fourth period, voltages held in the first and second storage capacitors are applied to a gate terminal of the first transistor to supply a current to a light-emitting element, so that the light-emitting element emits light. Through the operation process, a current obtained by compensating variations in the threshold voltage of the first transistor can be supplied to the light-emitting element, thereby variations in luminance can be suppressed.

    Abstract: In a video voltage comparator circuit, an average of first video voltages applied to pixel electrodes of pixels in the second-half rows in a k-th frame period (k is a natural number) is compared with an average of second video voltages applied to pixel electrodes of pixels in the first-half rows in a (k+1)th frame period for each row. In an overdrive voltage switching circuit, when a difference obtained from the comparison in the video voltage comparator circuit is greater than or equal to a threshold value, the overdrive voltage in the (k+1)th frame period is switched to a first overdrive voltage, and when the difference obtained from the comparison in the video voltage comparator circuit is less than the threshold value, the overdrive voltage in the (k+1)th frame period is switched to a second overdrive voltage lower than the first overdrive voltage.
