Patent ID: 7547918

Claim:
An active matrix substrate, comprising: a substrate; a plurality of signal lines; a plurality of scanning lines intersecting with the signal lines; switching elements, each being arranged nearby a portion where one of the signal lines intersects with one of the scanning lines; a peripheral line having at least a function of supplying signals to the signal lines and the scanning lines, the signal lines, the scanning lines, the switching elements, and the peripheral line being provided on the substrate; and the active matrix substrate further comprising: a protection layer formed on the substrate; a resin layer formed on the protection layer; a groove configured in the protection layer and the resin layer or configured in the substrate; and a conductive auxiliary member filled in the groove and in continuous longitudinal contact along a substantial length of one of said signal lines, said scanning lines or said peripheral line on said active matrix substrate so as to lower a combined resistance value of the conductive auxiliary member and one of the signal lines, said scanning lines or said peripheral line.
