1. A method of manufacturing a display panel, the method comprising:
providing a first signal pad on a first face of a substrate;
providing a second signal pad on a second face of the substrate;
providing a conductive member that contacts each of the first signal pad, the second signal pad, and a third face of the substrate;
providing a photoresist member that partially covers the conductive member and overlaps each of the first signal pad, the second signal pad, and the third face of the substrate;
pre-curing the photoresist member;
forming a signal line by etching the conductive member; and
curing the photoresist member to form a cured photoresist member, wherein in cured photoresist member covers an edge of the signal line.
