Abstract:
1. A display device comprising: a pixel array formed by arranging a plurality of pixels whose display grayscales are controlled according to a pixel signal written, in the row direction and in the column direction; a signal line drive unit that outputs a pixel signal with respect to each pixel, to a plurality of signal lines arranged in the pixel array, with a polarity according to a polarity signal, every one line period defined by a vertical clock; a scan line drive unit that sequentially drives a plurality of scan lines arranged in the pixel array and performs a writing of the pixel signal output to the signal line into the pixels in each line, every vertical clock timing, during one frame period starting with a timing of a vertical start pulse; a polarity signal generation unit that generates the polarity signal, the polarity signal instructing the polarity of the pixel signal to be reversed in an N line period cycle and being asynchronous with respect to the vertical start pulse, and supplies the result to the signal line drive unit; and a frame cycle set unit that generates the vertical start pulse in such a manner that a period of the number of vertical clocks that is not a multiple of the N is one frame period, where N is a positive integer.
