Abstract
A method for driving a display device in an embodiment according to the present invention, the method including step of displaying an image in accordance with a first video signal in a first frame period, and displaying the image in accordance with the first video signal after the first frame in a second frame period. The image in the first frame period is displayed after an end of a non-display period, the non-display period is shorter than the first frame period, and the non-display period is inserted after writing of the video signal in the first frame period and before display of the image.
