PROBLEM TO BE SOLVED: To provide a display device which can perform clear display by increasing contrast in display by solving the problem that a light emitting element slightly emits light by an off current of a thin film transistor connected in series to the light emitting element, and a driving method therefor.MEANS FOR SOLVING THE PROBLEM: When the thin film transistor connected in series to the light emitting element is turned off, a charge held in 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, the off current charges this capacitance until 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.SELECTED DRAWING: Figure 1 |
