Abstract
It is an object of the present invention to provide a display device in which problems such as an increase of power consumption and increase of a load of when light is emitted are reduced by using a method for realizing pseudo impulsive driving by inserting an dark image, and a driving method thereof. A display device which displays a gray scale by dividing one frame period into a plurality of subframe periods, where one frame period is divided into at least a first subframe period and a second subframe period; and when luminance in the first subframe period to display the maximum gray scale is Lmax1 and luminance in the second subframe period to display the maximum gray scale is Lmax2, (½) Lmax2<Lmax1<( 9/10) Lmax2 is satisfied in the one frame period, is provided.
