    摘要： A light emitting device and an element substrate which are capable of suppressing variations in the luminance intensity of a light emitting element among pixels due to characteristic variations of a driving transistor without suppressing off-current of a switching transistor low and increasing storage capacity of a capacitor. According to the invention, a driving transistor also serves as an erasing transistor and the driving transistor is operated in a saturation region. The gate of the driving transistor is connected to an erasing scan line and it can be selected whether or not to flow current by a potential of the erasing scan line. In addition, a current controlling transistor which operates in a linear region is connected in series to the driving transistor, thus a video signal transmitting a light emission or non-emission of a pixel is input to the gate of the current controlling transistor through a switching transistor.

    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
