Polarizing substrate, display panel and manufacturing method thereof

A polarizing substrate comprises a substrate, a plurality of first metal wires and a plurality of second metal wires. The first metal wires are located on the substrate, and the first metal wires are arranged at a first interval and are parallel to each other. The second metal wires are located on the first metal wires, the second metal wires are arranged at a second interval and are parallel to each other, and the second metal wires make contact with and intersect with a part of the first metal wires. 偏光基板包括基板、多条第一金属线以及多条第二金属线。第一金属线位于基板上，第一金属线以第一间距排列且互相平行。第二金属线位于第一金属线上，第二金属线以第二间距排列且互相平行，且第二金属线接触并相交于一部分的第一金属线。
