To provide a wiring structure with which resistance difference between laying wires is reduced, and a display device using the same.

The wiring structure includes a first conductive layer formed on a substrate, a second conductive layer, and an insulating film arranged between the first conductive layer and the second conductive layer, and includes: a plurality of scanning wires 3 (or signal wires 4) formed of the first conductive layer; a first routing wire 61 formed of the first conductive layer and separated from the wires; a first connecting portion 91 to electrically connect the first routing wire 61 to the wires; a second routing wire 62 formed of the second conductive layer and prepared for wires, out of the plurality of wires, which are not connected to the first rounting wire 61; and a second connecting portion 92 to connect the second routing wire 62 to the wires.
