Patent ID: 7864281

Claim:
An active matrix substrate comprising: a substrate; a plurality of scanning lines arranged on the substrate; an insulating film covering the plurality of scanning lines; a plurality of signal lines intersecting the plurality of scanning lines via the insulating film; a plurality of switching elements arranged on the substrate, each operating in response to a signal which is applied to the corresponding scanning line; and a plurality of pixel electrodes each capable of being electrically connected to the corresponding signal line via the plurality of switching elements, wherein, the insulating film is a multilayer insulating film including a first insulating layer and a second insulating layer; the first insulating layer is made of an insulating material containing an organic component; the multilayer insulating film has a low-stack region in at least a portion of a region overlapping each switching element, the first insulating layer not being located in the low-stack region; and the first insulating layer is arranged to underlie the second insulating layer.
