摘要:
A drive section sequentially supplies respective scanning lines with a control signal and supplies respective signal lines with a video signal to carry out a correction operation for holding a voltage equivalent to a threshold voltage of a drive transistor in a holding capacitance, and subsequently performs a write operation for writing the video signal in the holding capacitance, and before the correction operation, the drive section switches potentials at the bias line and adds a coupling voltage to one current terminal of the drive transistor via an auxiliary capacitance to carry out a preparation operation for an initialization to set a potential difference between a control terminal and the one current terminal of the drive transistor larger than the threshold voltage.
