DRIVER CIRCUIT, DISPLAY DEVICE INCLUDING THE DRIVER CIRCUIT, AND ELECTRONIC DEVICE INCLUDING THE DISPLAY DEVICE |
摘要 |
One object is, when a thin film transistor whose channel is formed using an amorphous semiconductor is used for a driver circuit formed using only n-channel transistors or p-channel transistors, to provide a driver circuit in which the threshold voltage is compensated in accordance with the degree of change in the threshold voltage. In the driver circuit which includes a unipolar transistor including a first gate and a second gate which are disposed above and below a semiconductor layer with insulating layers provided therebetween, a first signal for controlling switching of the transistor is inputted to the first gate, a second signal for controlling a threshold voltage of the transistor is inputted to the second gate, and the second signal is controlled in accordance with a value of current consumption including a current which flows between a source and a drain of the transistor.
