ABSTRACT:
In one embodiment, a display device of the present invention includes capacitors provided between a gate and a source of a driver TFT. During a select period, a voltage is fed to the gate terminal of the driver TFT, and a voltage is fed to the source terminal of the driver TFT. Thereafter, during a threshold correction period, the gate voltage of the driver TFT is retained to make the source voltage of the driver TFT equal to Vda−Vth (<Vcom). Subsequently, the gate voltage of the driver TFT is changed to control a current flowing between the drain and the source of the driver TFT.
