A slim border electronic device comprising a trace structure, wherein:

• the trace structure comprises:
• a substrate;
• a first conductive metal trace disposed in a peripheral area of the substrate;
• and
• a first conductive composite layer disposed between the first conductive metal trace and the substrate, wherein the first conductive composite layer comprises silver nanowires embedded in a polymer, the first conductive metal trace has a lower electric resistance than the first conductive composite layer, and a conductive metal side surface of the first conductive metal trace aligns with a side surface of the first conductive composite layer,
• and
• a width of a peripheral area of the slim border electronic device is about 2 mm or smaller.
