Patent ID: 8149197

Claim:
An electro-optical display device, comprising: an electro-optical panel including a plurality of scanning lines, a plurality of data lines intersecting with the corresponding scanning lines, and a plurality of pixels disposed at intersections of the corresponding scanning lines and data lines; a scanning line drive circuit for scanning the scanning lines by supplying a scanning signal to at least one of the scanning lines during a selection period; and a data line drive circuit for outputting a data signal to a predetermined pixel through the corresponding data line in synchronization with the scanning of the scanning line drive circuit, wherein, during the selection period during which the data signal is output to the predetermined pixel, said data signal comprises an OFF voltage interval and an ON voltage interval, said ON voltage interval causing the predetermined pixel to display one of a plurality of grayscale levels in accordance with a duration of said ON voltage interval, and wherein the duration (T 0 ) of the ON voltage interval corresponding to a grayscale level having a longest OFF voltage interval is set to be longer than the duration (T N ) of the OFF voltage interval corresponding to a grayscale level having a longest ON voltage interval.
