Abstract
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 bunched together, a first inspection wiring (66) capable of inputting an inspection signal to bunched 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.
