Title: Display device and method of driving same

Abstract: A display device has a matrix array of pixels, each provided with a switching element operated by a scanning signal and a pixel electrode supplied with a video signal via the switching element. A method of driving a display device includes selecting of a row of pixels successively in a matrix array of pixels, and supplying of a video signal to each of the selected pixels. A gray scale is produced by writing binary signals into each of the pixels at plural times within one field period, based upon information represented by plural bits. The writing of binary signals is performed by turning on the switching element for one of plural approximately equal portions into which a unit basic scanning period is divided, the unit basic scanning period being a subdivision of one field period, and time intervals between the plural times are selected to be successively shorter.
