Abstract
An active matrix substrate includes, in a peripheral region that is disposed around a display region, a connecting portion formation region in which a plurality of line connecting portions are arranged. Each line connecting portion includes: a lower connecting portion; an organic insulating layer disposed on the lower connecting portion so as to be in contact with the lower connecting portion, the organic insulating layer having at least one aperture through which a part of the lower connecting portion is exposed; and an upper connecting portion disposed on the organic insulating layer and in the at least one aperture, the upper connecting portion being directly in contact with the part of the lower connecting portion within the at least one aperture. The organic insulating layer extends into an adjoining region that adjoins the connecting portion formation region. In the adjoining region, the organic insulating layer has a plurality of dummy apertures that are disposed so as not to overlap the lower connecting portions when viewed from the normal direction of the substrate, each dummy aperture exposing a part of an underlying layer that is located on the substrate side of the lower connecting portion. The upper connecting portions are not provided in the plurality of dummy apertures.
