Abstract
This present invention provides a liquid-crystal panel that presents a high-density wiring while maintaining reliability of the wiring. Odd-numbered scanning lines are connected to a first wiring group while even-numbered scanning lines are connected to a second wiring group. Each of the scanning lines is supplied with a scanning signal the polarity of which is inverted every horizontal scanning period. Among wirings forming the first wiring group and the second wiring group, a line-to-line voltage between any adjacent wirings becomes zero volt for a majority of the time. Accordingly, degradation of the wirings due to electrolytic corrosion is controlled even if the spacing between the wirings is narrowed.
