摘要： In a display apparatus including a switching transistor, 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.

摘要： Disclosed herein is a display apparatus including a pixel array section and a drive section. The pixel array section has power supply lines, scan lines arranged in row, signal lines arranged in column, and pixels arranged in matrix at intersections of each of the scan lines and each of the signal lines. The drive transistor is connected at one of a pair of current terminals to the light emitting device and at the other of the pair of current terminals to the power supply line. The drive section supplies a control signal to each scan line and a video signal to each signal line to drive each pixel, executing a threshold voltage correcting operation, a write operation, and a light emitting operation.
