Abstract
A display device includes a display panel having display elements, arranged in a matrix, a drain driver which supplies gradation voltages corresponding to image data to the display elements, a gate driver which scans lines of the display elements for supplying the gradation voltage, and a data generation circuit which divides image data for one frame into a plurality of pieces of sub-field image data in a time direction. The data generation circuit operates to convert one piece of sub-field image data into bright gradation data which has a higher brightness than the inputted image data which has been inputted, and to convert another piece of sub-field image data into dark gradation data which has a lower brightness than the inputted image data.
