Claim:
A display device comprising: a pixel array comprised of two-dimensionally arranging pixels, each including an electro-optic element, in a matrix, the pixel array divided into N areas in a vertical direction, where N is an integer of 2 or more; N vertical driving circuits, each corresponding to one of the N areas of the pixel array and configured to, in each field period, output drive pulses to sequentially select each row of pixels of the corresponding area, such that rows of pixels selected by the N vertical driving circuits sequentially alternate among the N areas; and a horizontal driving circuit configured to output a video signal inverted in polarity in each horizontal period to pixels of the row selected by the N vertical driving circuits, wherein, the polarity of the video signal output to each row of pixels is inverted between two successive field periods, the N vertical driving circuits sequentially generate a drive pulse for selecting the pixels in a row of pixels on a basis of a second vertical start pulse and a second vertical driving clock having pulse widths N times respective pulse widths of a first vertical start pulse and a first vertical clock pulse used when scanning is performed sequentially without the pixel array unit being divided, and each vertical driving circuit includes (i) a shift register that performs transfer operation in synchronism with the second vertical driving clock in response to the second vertical start pulse, and sequentially outputting a transfer pulse from each transfer stage, and (ii) a first logical product circuit group that obtains a logical product of a transfer pulse of an own stage and a transfer pulse of a next stage, the transfer pulses being output from the shift register, and an enable pulse having a period of ½N of a period of the second vertical clock pulse and having a pulse width narrower than ½N of a pulse width of the second vertical clock pulse.
