An active matrix substrate includes: a plurality of scan lines and signal lines on a transparent insulative substrate which cross each other; a plurality of switching elements formed at predetermined intersections of the scan lines and signal lines, the switching elements being electrically connected to the scan lines and signal lines; a connection electrode electrically connected to a corresponding one of the switching elements; an interlayer insulating film formed over the scan lines, the signal lines, the connection electrode, and the switching elements; a contact hole formed in the interlayer insulating film over the connection electrode; and a pixel electrode at each intersection, the pixel electrode being electrically connected to the connection electrode through the contact hole, wherein each of the scan lines and signal lines includes an opaque electrode layer; and the contact hole is formed such that a portion of the contact hole exists outside the connection electrode.
