A method of driving an EL display device in which pseudo contours are difficult to be seen is provided. A method of driving an EL display device in which a plurality of pixels, each having a first TFT, a second TFT, a third TFT, and an organic EL element, are formed has the following: n+m display periods (where n and m are both natural numbers) appear in one frame period; the n+m display periods each correspond to one bit of a digital video signal among n bits of the digital video signal; a plurality of display periods, among the n+m display periods, correspond to the same bit of the digital video signal; and display periods corresponding to other bits of the digital video signal, among the n+m display periods, appear during the plurality of display periods.
