摘要： In a display device including a pixel in which a driving transistor and a light-emitting element connected to a source of the driving transistor are provided, a display defect is suppressed. Before a period in which the driving transistor supplies a current to the light-emitting element, a voltage which has substantially the same level as a voltage which is applied to one electrode and the other electrode of a capacitor is kept as a voltage between a gate and the source of the driving transistor in the period. Specifically, a node where the one electrode of the capacitor and the gate of the driving transistor are electrically connected to each other in the period is made in a floating state, and the other electrode of the capacitor and the source of the driving transistor are electrically connected to each other.

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.

摘要： A display device with reduced power consumption, high definition, and a slim bezel. Both of a writing operation and an erasing operation are performed by one gate driver that is mainly constituted by a shift register for selecting a row and a control circuit for switching between a writing operation and an erasing operation.

摘要： To provide a display device with little signal delay and a display device that can operate with low power consumption, parasitic capacitance between a common wiring that applies a common potential to a plurality of pixels and signal lines that input signals for driving the pixels is avoided. Specifically, the common wiring is routed outwardly with respect to an external input terminal to which a signal is input from the, outside, to avoid intersections of the signal lines and the common wiring. Thus, parasitic capacitance between the common wiring and the signal lines is avoided, so that the display device can operate at high speed with low power consumption.
