Wiring device and display device

A wiring device, disposed on a substrate, the wiring device comprising:

• at least one main conductive line, disposed on the substrate;
• a plurality of branch conductive lines, disposed on the substrate, wherein each of the branch conductive lines is electrically connected to the main conductive line;
• a passivation layer, disposed on the branch conductive lines;
• a plurality of contact holes partially exposing each of the branch conductive lines in an at least one contact hole to one branch conductive line correspondence;
• a plurality of conductive patterns, disposed on the passivation layer, wherein each of the conductive patterns is disposed respectively corresponding to each of the branch conductive lines, and each of the conductive patterns is electrically connected to the corresponding branch conductive line via the contact holes;
• and
• a plurality of outside device bonding regions, each of the outside device bonding regions disposed uniquely corresponding to one of the branch conductive lines, wherein at least one of the outside device bonding regions does not overlap any one of the contact holes in a vertical projective direction.
