摘要： A display device includes a pixel array unit having a matrix of pixels each configured such that an anode electrode of an organic electroluminescent element is connected to a source electrode of a drive transistor, a gate electrode of the drive transistor is connected to a source or drain electrode of a writing transistor, and a storage capacitor is connected between the gate and source electrodes of the drive transistor, scanning lines and power supply lines for individual pixel rows, and signal lines for individual pixel columns. A video signal reference potential is supplied to the signal lines for a period during which a scanning signal is supplied to the scanning lines during driving of pixels in a preceding row. During threshold correction for the drive transistor in a current pixel, the video signal reference potential and a potential of the cathode electrode of the organic electroluminescent element are equal.

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.
