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.

Abstract: To construct an unbreakable probe for inspecting a liquid crystal display panel, and to substantially reduce a manufacturing cost thereof, a plurality of terminals subjected to patterning on a probe unit 280 having flexibility are contacted to a plurality of terminals of scanning lines formed on a substrate 200. A plurality of terminals subjected to patterning on a probe unit 380 having flexibility are contacted to a plurality of terminals of data lines formed on a substrate 300 each other. A driving signal for driving the scanning lines is supplied to respective scanning lines via the terminals subjected to patterning on the probe unit 280, while a driving signal for driving the data lines is supplied to respective data lines via the terminals subjected to patterning on the probe unit 380.
