    摘要： A pixel circuitry of a display device is provided to make a voltage level transmitted to a display element be close to a voltage level of a received data voltage, such that the pixel circuitry faithfully transmits the data voltage to the display element. The pixel circuitry of a display device includes a first write switch, a first write memory unit, a first voltage following module, and a display element. The first voltage following module is to detect a first data voltage stored in the first write memory unit, and to generate a corresponding first output voltage at a terminal of the display element based on a detection result. A first output terminal of the first voltage following module is controlled by a switching voltage.

    摘要： A transistor has variation in a threshold voltage or mobility due to accumulation of factors such as variation in a gate insulating film which is caused by a difference of a manufacturing process or a substrate to be used and variation in a crystal state of a channel formation region. The present invention provides an electric circuit which is arranged such that both electrodes of a capacitance device can hold a voltage between the gate and the source of a specific transistor. Further, the present invention provides an electric circuit which has a function capable of setting a potential difference between both electrodes of a capacitance device so as to be a threshold voltage of a specific transistor.
