Wiring substrate, transparent display substrate, and tiled screen

A wiring substrate, comprising:

• a transparent substrate, comprising a first surface and a second surface opposite to each other, wherein the second surface comprises a wiring region and a bonding region arranged along a first direction, and a plurality of connecting through holes are arranged in the wiring region;
• a plurality of first-type wires, located on the first surface of the transparent substrate and in one-to-one correspondence with the plurality of connecting through holes, wherein the plurality of first-type wires are arranged at intervals along the first direction, each of the plurality of first-type wires extends along a second direction, and the first direction is perpendicular to the second direction;
• and
• a plurality of second-type wires, located on the second surface of the transparent substrate and in one-to-one correspondence with the plurality of first-type wires, wherein the plurality of second-type wires are arranged at intervals along the second direction, each of the plurality of second-type wires extends along the first direction, and each of the first-type wires is connected with a corresponding one of the second-type wires at a corresponding one of the connecting though holes.
