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.
