Zusammenfassung:An active matrix substrate for a liquid crystal panel of an FFS mode includes a plurality of connecting units in a connecting region in order to electrically connect a common electrode, a first common main wiring 31, and a second common main wiring 32. The connecting unit includes a contact hole 41 that connects a connecting electrode 37 and the first common main wiring 31, the connecting electrode 37 formed integrally with the common electrode, and a contact hole 42 that connects the connecting electrode 37 and the second common main wiring 32. An amorphous Si film 122 of the second common main wiring 32 is formed larger than a main conductor part 131 of the second common main wiring 32 in a position of the contact hole 41, and is covered with SiNx films 151, 152 that are protective insulating films. This prevents the connecting electrode from having a step disconnection at a pattern end of the common main wiring.
