Abstract
In one embodiment, a liquid crystal display device includes first and second areas respectively having a gate line group in an active area, and a dummy gate line group arranged on an outside of the active area. A driving circuit selects the gate lines of the gate line group and the dummy gate lines of the dummy gate line group one by one in the first and second areas. The driving circuit is independently controlled for the first and second areas. The gate lines are scanned from a center portion of the active area to the dummy gate line side in the first and second areas, respectively. An image signal and a non-image signal are written within one-frame period in the first and second areas.
