Active matrix substrate, display device, method for inspecting the active matrix substrate, and method for inspecting the display device

摘要

An active matrix substrate (2) is provided with first connecting wirings (641, 643, 645, 647) connected to gate terminals (51) to which extraction wirings (611, 613, 615, 617) are connected, second connecting wirings (642, 644, 646) connected to gate terminals (51) to which extraction wirings (612, 614, 616) are connected, bundled wirings (651 to 654) each composed of a mutually adjacent first connecting wiring and second connecting wiring bundled together, a first inspection wiring (66) capable of inputting an inspection signal to bundled wirings (652, 654) that are not adjacent to each other among the bundled wirings, and a second inspection wiring (67) capable of inputting an inspection signal to bundled wirings (651, 653) that are not adjacent to each other and not connected to the first inspection wiring (66) among the bundled wirings.

主权项

1. An active matrix substrate comprising:
a plurality of first wirings formed parallel to each other in a display region; a plurality of first terminals arranged in a terminal arrangement region; and a plurality of first extraction wirings respectively connecting the plurality of first wirings and the plurality of first terminals; wherein the plurality of first extraction wirings are respectively connected, through the first terminals, to one of second wirings and third wirings, both of which are formed adjacently and alternately in an arrangement direction of the plurality of first extraction wirings in a region other than the display region, and the active matrix substrate comprises a common wiring connected to a plurality of bundled wirings that are composed of the second wirings and the third wirings, respectively.
