ABSTRACT:
An active matrix liquid crystal panel comprises an active matrix substrate, on which a plurality of parallel signal lines and a plurality of parallel scanning lines are arranged for forming a matrix of pixels. The second common electrodes formed in an upper layer where comb-shaped pixels exist have a plurality of apertures. When the signal line has a breakage, a cutting means can cut the two ends of the root trace connected to a closed-loop branch through one of the apertures, and a welding means can weld the broken signal line and the isolated closed-loop branch extended from a first common electrode in a lower layer together through one aperture and another.
