Claim 7:
8. The active matrix substrate according to claim 2,
wherein the active matrix substrate includes a display region including a plurality of pixel areas and a non-display region located around the display region,
each of the plurality of thin film transistors and each of the plurality of pixel electrodes are arranged in the display region in association with one of the plurality of pixel areas,
the non-display region includes at least one groove region, each of the at least one groove region including a first groove extending in a first direction when viewed from the normal direction of the substrate,
the first groove includes
the gate insulating layer,
the interlayer insulating layer including a groove exposing part of the gate insulating layer and extending in the first direction when viewed from the normal direction of the substrate,
an insulating layer formed of the first dielectric film, in direct contact with the gate insulating layer in the groove, and extending in the first direction when viewed from the normal direction of the substrate, and
the first dielectric layer covering an upper face of the interlayer insulating layer and at least part of a side surface of the groove, and
the insulating layer includes two edge portions facing each other and extending in the first direction when viewed from the normal direction of the substrate, the two edge portions being each located between the interlayer insulating layer and the gate insulating layer.
