Abstract:
1. A display device comprising: a pixel array section including pixels arranged in a matrix form, each pixel having an electro-optical element, a write transistor adapted to sample and write an input signal voltage, a holding capacitance adapted to hold the input signal voltage written by the write transistor and a drive transistor adapted to drive the electro-optical element based on the input signal voltage held by the holding capacitance; and a scan circuit including a final stage buffer, whose power supply is separated from circuit portions of a previous stage, and configured to apply a scan signal from the previous stage buffer to the write transistor to select and scan the pixels in the pixel array section on a row by row basis; wherein a supply voltage in pulse form is supplied to the power supply of the final stage buffer so that the scan signal rises at the leading edge of the supply voltage.
