Abstract:
1. An active matrix substrate comprising: a plurality of first wirings formed parallel to each other in a display region; a plurality of second wirings formed parallel to each other and so as to intersect the plurality of first wirings in the display region; a plurality of first terminals arranged in a terminal arrangement region; a plurality of second terminals arranged in the terminal arrangement region; a plurality of first extraction wirings respectively connecting the plurality of first wirings and the plurality of first terminals; and a plurality of second extraction wirings respectively connecting the plurality of second wirings and the plurality of second terminals, wherein the plurality of first extraction wirings include a plurality of third extraction wirings and a plurality of fourth extraction wirings, the third extraction wirings being formed on the same layer as a layer on which the first wirings are formed, at least a portion of the fourth wirings being formed on a different layer from the layer on which the first wirings are formed with an insulating material sandwiched therebetween, and the third extraction wirings and the fourth extraction wirings being formed alternately per wiring in a peripheral wiring region that is other than the display region and the terminal arrangement region, and the active matrix substrate comprises: a plurality of first connecting wirings respectively connected to a plurality of first terminals to which the plurality of third extraction wirings are respectively connected; a plurality of second connecting wirings respectively connected to a plurality of first terminals to which the plurality of fourth extraction wirings are respectively connected; a plurality of bundled wirings each composed of a mutually adjacent first connecting wiring and second connecting wiring bundled together; a first common wiring commonly connecting bundled wirings that are not adjacent to each other among the plurality of bundled wirings; and a second common wiring commonly connecting bundled wirings that are not adjacent to each other and not connected to the first common wiring among the plurality of bundled wirings.
