Abstract
An organic EL display device includes a transistor for controlling whether to shut off supply of a current to an organic EL element or not, a pulse signal generation circuit which generates a pulse signal to be inputted to the transistor and a storage unit. The storage unit stores the information in such a way that one frame period includes, in order, a first light emission period which is a period preceding a pulse, a black display period which is a period equivalent to a width of the pulse, and a second light emission period which is longer than the first light emission period, and that an area expressed by a product of a length of and a luminance in a light emission period is greater for the second light emission period than for the first light emission period.
