ABSTRACT:
An active matrix substrate includes a substrate; scanning lines formed on the substrate; an insulating film covering the scanning lines; signal lines intersecting the scanning lines via the insulating film; switching elements formed on the substrate, each operating in response to a signal which is applied to the corresponding scanning line; and pixel electrodes each capable of being electrically connected to the corresponding signal line via the switching elements. The insulating film is a multilayer insulating film including a first insulating layer and a second insulating layer. The first insulating layer is formed of an insulating material containing an organic component, and 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 formed in the low-stack region. The active matrix substrate reduces the capacitance formed at each intersection between a scanning line and a signal line, without causing an increase in the wiring resistance or a degradation of the driving ability of switching elements.
