摘要： The invention provides a pixel circuit that allows simultaneous correction of both influence of the threshold voltage of a drive transistor and influence of the mobility of the drive transistor. Correction means is connected to a drive transistor and a capacitance part, and operates during a correction period preceding to a sampling period. The correction period is separated into a reset period and a detection period. During the reset period, the correction means energizes the capacitance part to reset the potential of the capacitance part. During the detection period, the correction means stops the energization and detects the potential difference arising between the source and gate of the drive transistor during the period when a transient current flows through the drive transistor. The capacitance part holds the potential corresponding to the detected potential difference. The held potential includes both a potential component for reducing the influence of the threshold voltage on the output current of the drive transistor, and a potential component for reducing the influence of the carrier mobility thereon.
