摘要： No need of lowering off-current of a switching transistor, fewer luminance variations of a light emitting element between pixels due to characteristic variations of a driving transistor, and less risk of steps due to increase in the number of wirings. A video signal for light emission or non-emission of a pixel is input to a gate of a current controlling transistor operated in a linear region, which is connected in series with the driving transistor, through a switching transistor. Since a voltage Vds between a source and a drain of the current controlling transistor is small, small changes in a voltage Vgs between a gate and a source thereof do not affect a current flowing in a load. The current flowing in the light emitting element is determined by the driving transistor operated in a saturation region, and a fixed potential is input to the gate thereof during light emission.

摘要： When a thin film transistor has an LDD structure or a double gate structure, the number of manufacturing steps increases, which may decrease the yield. The invention provides a display device where the influence of off current is reduced by a method different from the conventional one. According to the invention, a pass element is provided at one electrode of a light emitting element so as not to flow the off current of a transistor for driving the light emitting element through the light emitting element in a non-lighting period. The pass element allows the off current to flow outside, that is, the off current can be bypassed outside through the pass element.
