摘要： A pixel circuit, disposed at a part where a scanning line and a signal line intersect each other, includes at least an electrooptic element, a drive transistor, a sampling transistor, and a retaining capacitance. The drive transistor has a gate connected to an input node, a source connected to an output node, and a drain connected to a predetermined power supply potential and supplies a driving current to the electrooptic element according to a signal potential retained in the retaining capacitance. The electrooptic element has one terminal connected to the output node and another terminal connected to a predetermined potential. The sampling transistor is connected between the input node and the signal line and operates when selected by the scanning line, samples an input signal from the signal line, and retains the input signal in the retaining capacitance. The retaining capacitance is connected to the input node. The pixel circuit further includes a compensating circuit which detects a decrease in the driving current from a side of the output node and feeds back a result of detection to a side of the input node to compensate for a decrease in the driving current, which decrease is attendant on a secular change of the drive transistor.

摘要： In a display apparatus including a correction unit and a switching transistor, the correction unit operates in a non-light emission period such that a correction voltage for eliminating an effect of a variation in a characteristic of a driving transistor is stored in a storage capacitor. The switching transistor is disposed between one current terminal of the driving transistor and a light emitting element. The switching transistor turns off during the non-light emission period thereby to electrically disconnect the light emitting element from the one current terminal of the driving transistor thereby preventing a leakage current from flowing through the light emitting element during the period in which the correction unit operates, and thus preventing the correction voltage from having an error due to the leakage current.
