摘要： A low power consumption shift register which inputs a CK signal with a low voltage with almost no effect of variation in characteristics of transistors. In the invention, an input portion of an inverter is set at a threshold voltage thereof and a CK signal is inputted to the input portion, of the inverter through a capacitor means. In this manner, the CK signal is amplified, which is sent to the shift register. That is, by obtaining the threshold potential of the inverter, the shift register which operates with almost no effect of variation in characteristics of transistors can be provided. A level shifter of the CK signal is generated from an output pulse of the shift register, therefore, the low power consumption shift register having the level shifter which flows a shoot-through current for a short period can be provided

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： Semiconductor elements deteriorate or are destroyed due to electrostatic discharge damage. The present invention provides a semiconductor device in which a protecting means is formed in each pixel. The protecting means is provided with one or a plurality of elements selected from the group consisting of resistor elements, capacitor elements, and rectifying elements. Sudden changes in the electric potential of a source electrode or a drain electrode of a transistor due to electric charge that builds up in a pixel electrode is relieved by disposing the protecting means between the pixel electrode of the light-emitting element and the source electrode or the drain electrode of the transistor. Deterioration or destruction of the semiconductor element due to electrostatic discharge damage is thus prevented.
