Abstract
A display device includes: on an insulating substrate, a first conductive layer in which a first signal line and a second signal line adjacent to the first signal line are formed; an insulating layer which is disposed on the first conductive layer; a second conductive layer which is disposed on the insulating layer and in which a ground wire crossing the first signal line and the second signal line in a plan view is formed; and a semiconductor layer which is disposed between the insulating layer and the second conductive layer and in which a first semiconductor film and a second semiconductor film are formed to be separated from each other. The wiring lengths of the first signal line and the second signal line are different by at least 10 times or more. The first semiconductor film overlaps, in a plan view, a region where the first signal line crosses the ground wire. The second semiconductor film overlaps, in a plan view, a region where the second signal line crosses the ground wire.
