Patent ID: 7336252

Claim:
An image display device comprising: a first display panel having a substrate on which a plurality of first scanning lines which extend in the first direction and are arranged in parallel in the second direction which intersects the first direction and a plurality of first signal lines which extend in the second direction and are arranged in parallel in the first direction are formed; a second display panel having a substrate on which a plurality of second scanning lines which extend in the first direction and are arranged in parallel in the second direction, the second scanning lines being smaller than the first scanning lines in number, and a plurality of second signal lines which extend in the second direction and are arranged in parallel in the first direction, the second signal lines being connected to the first signal lines and being smaller than the first signal lines in number are formed; a scanning line drive circuit capable of supplying scanning signals to the first scanning lines and the second scanning lines; a signal line drive circuit capable of supplying signals to the first signal lines and the second signal lines; an image memory having at least a display data capacity to be displayed on the first display panel; and a display control device which controls display operations of the first display panel and the second display panel; wherein the display control device drives the first display panel in a line inversion mode when images are displayed only on the first display panel and drives the second display panel in a frame inversion mode when images are displayed only on the second display panel; and wherein the display control device drives both of the first display panel and the second display panel in the line inversion mode when images are displayed on both of the first display panel and the second display panel.
