ABSTRACT:
The present invention relates to a hold type display device.One frame period that is a period when an image of one screen is displayed is divided into a dark display period when a relatively dark image is displayed and a bright display period when a relatively bright image is displayed. In the dark display period, each of scanning signal lines (GL1, GL2, GL3, etc.) is driven consecutively two times each during a period corresponding to one third of a conventional one horizontal scanning period. Also, in the dark display period, each two lines of the scanning signal lines (GL1, GL2, GL3, etc.) is driven at the same time. A gradation is calculated for generating a video signal such that, at two pixel formation portions arranged at intersections of these two scanning signal lines driven at the same time and a video signal line, a luminance averaged from luminances originally to be appeared at the two pixel formation portions appears.
