Abstract
A display device in accordance with the present invention changes to Vc the voltage of a terminal of a capacitor Cthe other terminal of which is connected to the gate of a driver TFT Q. Thus, a desired voltage Vda is fed from a source line Sj to the drain of the driver TFT Qso as to adjust the threshold voltage Vth of the driver TFT Q. The device then changes the voltage of the terminal of the capacitor Cto Va to render the gate voltage of the driver TFT QVda-Vth-Vc+Va. A power supply voltage Vp is fed from the source of the driver TFT Q
