Abstract:
1. A display device comprising: a pixel array section; and a drive section, the pixel array section including scanning lines arranged in rows, signal lines SL arranged in columns, pixels arranged in matrix at positions where the scanning lines respectively intersect with the signal lines, and bias lines arranged in parallel to the respective scanning lines, each of the pixels at least including a sampling transistor, a drive transistor, a light emitting element, a holding capacitance, and an auxiliary capacitance, a control terminal of the sampling transistor being connected to the scanning line, and current terminals in pair of the sampling transistor being connected between the signal line and a control terminal of the drive transistor, one of current terminals in pair of the drive transistor being connected to the light emitting element, and the other terminal being connected to the power supply line, the holding capacitance being connected between the control terminal and the one current terminal of the drive transistor, and the auxiliary capacitance being connected between the one of current terminals of the drive transistor and the bias line, wherein the drive section sequentially supplies the respective scanning lines with a control signal and supplies the respective signal lines with a video signal to carry out a correction operation for holding a voltage equivalent to a threshold voltage of the drive transistor in the 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 the one current terminal of the drive transistor via the auxiliary capacitance to carry out a preparation operation for an initialization to set a potential difference between the control terminal and the one current terminal of the drive transistor larger than the threshold voltage.
