Abstract
An object of the present invention is to, in an organic EL display device in which an initialization voltage is applied, extend the time period usable to write a video voltage as compared with the conventional art. In order to achieve this object, the organic EL display device includes a plurality of pixels each including an organic EL element; a plurality of video lines that supply a video voltage to each of the plurality of pixels; a plurality of scanning lines that supply a scanning voltage to each of the plurality of pixels; a unit that supplies a selection scanning voltage concurrently to an N number of scanning lines among the plurality of scanning lines, and supplies an initialization voltage to each of the plurality of video lines, in a k'th scanning period; and a unit that supplies a selection scanning voltage sequentially to the N number of scanning lines, and supplies video voltages to each of the plurality of video lines, in (k+1)th through (k+N)th scanning periods respectively. N is an integer of 2 or greater (2≦N) and k is any positive integer.
